Mike Frysinger 44f6310bf9 newlib: libc: include all chapters all the time in the manual
THe stdio subdir is actually required by the documentation.  The
stdio/def is handled dynamically, but libc.texi always expects it
to be included, and fails if it isn't.  So making it required when
building docs is safe.

The xdr subdir is handled dynamically, but it doesn't include any
docs, so the dynamic logic isn't (currently) adding any value.  So
making it required when building docs is safe.

That leaves: iconv, stdio64, posix, and signal subdirs.  The chapters
have a little disclaimer saying they are system-dependent, but even
then, imo having stable manuals regardless of the target is preferable,
and we can add more disclaimer language to these chapters if we want.

This doesn't touch the man page codepaths, just the info/pdf.

Mike Frysinger 6444f108d9 newlib: export abs_newlib_basedir for all subdirs
When using the top-level configure script but subdir Makefiles, the
newlib_basedir value gets a bit out of sync: it's relative to where
configure lives, not where the Makefile lives.  Move the abs setting
from the top-level configure script into acinclude.m4 so we can rely
on it being available everywhere.  Although this commit doesn't use
it anywhere, just lays the groundwork.

Mike Frysinger 08a55a233d newlib: libc: merge machine/ configure scripts up a level
The machine configure scripts are all effectively stub scripts that
pass the higher level options to its own makefile.  There were only
three doing custom tests.  The rest were all effectively the same as
the libc/ configure script.

So instead of recursively running configure in all of these subdirs,
generate their makefiles from the top-level configure.  For the few
unique ones, deploy a pattern of including subdir logic via m4:
	m4_include([machine/nds32/acinclude.m4])

Some of the generated machine makefiles have a bunch of extra stuff
added to them, but that's because they were inconsistent in their
configure libtool calls.  The top-level has it, so it exports some
new vars to the ones that weren't already.

Mike Frysinger 8bee45444f newlib: libc: merge most sys/ configure scripts up a level
The sys configure scripts are almost all effectively stub scripts that
pass the higher level options to its own makefile.  The phoenix & linux
ones are a bit more complicated with nested subdirs, so those have been
left alone for now.  Plus, I don't really have a way of testing them.

Mike Frysinger f159663b08 newlib: stop clobbering LDFLAGS with non-standard $ldflags
It's unclear why this was added originally, but assuming it was needed
20 years ago, it shouldn't be explicitly required nowadays.  Current
versions of autotools already take care of exporting LDFLAGS to the
Makefile as needed (things are actually getting linked).  That's why
the configure diffs show LDFLAGS still here, but shifted to a diff
place in the output list.  A few dirs stop exporting LDFLAGS, but
that's because they don't do any linking, only compiling, so it's
correct.

As for the use of $ldflags instead of the standard $LDFLAGS, I can't
really explain that at all.  Just use the right name so users don't
have to dig into why their setting isn't respected, and then use a
non-standard name instead.  Adjust the testsuite to match.

Mike Frysinger 4317e0676a newlib: stop checking --enable-multilib in subdirs
None of the subdirs actually use the multilib arg, so include the
logic only in the top-level configure.

Mike Frysinger 6746e06043 newlib: avoid duplicate awk checks
Since AM_INIT_AUTOMAKE calls AC_PROG_AWK, and some configure.ac
scripts call it too, we end up testing for awk multiple times.  If
we change NEWLIB_CONFIGURE to require the macro instead, then it
makes sure it's always expanded, but only once.

While we're here, do the same thing with AC_PROG_INSTALL since it
is also called by AM_INIT_AUTOMAKE, although it doesn't currently
result in duplicate configure checks.

Mike Frysinger 71086e8b2d newlib: delete (most) redundant lib_a_CCASFLAGS=$(AM_CCASFLAGS)
Since automake already sets per-library CCASFLAGS to $(AM_CCASFLAGS)
by default, there's no need to explicitly set it here.

Many of these dirs don't have .S files in the first place, so the rule
doesn't even do anything.  That can easily be seen when Makefile.in has
no changes as a result.

For the dirs with .S files, the custom rules are the same as the pattern
.S.o rules, so this is a nice cleanup.

The only dir that was adding extra flags (newlib/libc/machine/mn10300/)
to the per-library setting can have it moved to the global AM_CCASFLAGS
since the subdir only has one target.  Although the setting just adds
extra debugging flags, so maybe it should be deleted in general.

There are a few dirs that we leave the redundant setting in place.  This
is to workaround an automake limitation in subdirs that support building
with & w/out libtool:

Mike Frysinger 20e3103471 newlib: update to automake-1.15
This matches what the other GNU toolchain projects have done already.
The generated diff in practice isn't terribly large.  This will allow
more use of subdir local.mk includes due to fixes & improvements that
came after the 1.11 release series.

Mike Frysinger a100e80fc9 require autoconf-2.69 exactly
The newlib & libgloss dirs are already generated using autoconf-2.69.
To avoid merging new code and/or accidental regeneration using diff
versions, leverage config/override.m4 to pin to 2.69 exactly.  This
matches what gcc/binutils/gdb are already doing.

The README file already says to use autoconf-2.69.

To accomplish this, it's just as simple as adding -I flags to the
top-level config/ dir when running aclocal.  This is because the
override.m4 file overrides AC_INIT to first require the specific
autoconf version before calling the real AC_INIT.

Mike Frysinger 8fc6b4b30e newlib: regen aclocal.m4 after autoconf update
The configure scripts were regenerated with 2.69 for the newlib-4.2.0
release in 484d2ebf8d, but the aclocal
files were not.  Do that now to avoid confusion between the two as to
which version of autoconf was used.

Mike Frysinger ed20821a40 newlib: migrate from INCLUDES to AM_CPPFLAGS
Since automake deprecated the INCLUDES name in favor of AM_CPPFLAGS,
change all existing users over.  The generated code is the same since
the two variables have been used in the same exact places by design.

There are other cleanups to be done, but lets focus on just renaming
here so we can upgrade to a newer automake version w/out triggering
new warnings.

newlib: Remove automake option 'cygnus'
The 'cygnus' option was removed from automake 1.13 in 2012, so the
presence of this option prevents that or a later version of automake
being used.

A check-list of the effects of '--cygnus' from the automake 1.12
documentation, and steps taken (where possible) to preserve those
effects (See also this thread [1] for discussion on that):

[1] https://lists.gnu.org/archive/html/bug-automake/2012-03/msg00048.html

1. The foreign strictness is implied.

Already present in AM_INIT_AUTOMAKE in newlib/acinclude.m4

2. The options no-installinfo, no-dependencies and no-dist are implied.

Already present in AM_INIT_AUTOMAKE in newlib/acinclude.m4

Future work: Remove no-dependencies and any explicit header dependencies,
and use automatic dependency tracking instead.  Are there explicit rules
which are now redundant to removing no-installinfo and no-dist?

3. The macro AM_MAINTAINER_MODE is required.

Already present in newlib/acinclude.m4

Note that maintainer-mode is still disabled by default.

4. Info files are always created in the build directory, and not in the
source directory.

This appears to be an error in the automake documentation describing
'--cygnus' [2]. newlib's info files are generated in the source
directory, and no special steps are needed to keep doing that.

[2] https://lists.gnu.org/archive/html/bug-automake/2012-04/msg00028.html

5. texinfo.tex is not required if a Texinfo source file is specified.
(The assumption is that the file will be supplied, but in a place that
automake cannot find.)

This effect is overriden by an explicit setting of the TEXINFO_TEX
variable (the directory part of which is fed into texi2X via the
TEXINPUTS environment variable).

6. Certain tools will be searched for in the build tree as well as in the
user's PATH. These tools are runtest, expect, makeinfo and texi2dvi.

For obscure automake reasons, this effect of '--cygnus' is not active
for makeinfo in newlib's configury.

However, there appears to be top-level configury which selects in-tree
runtest, expect and makeinfo, if present. So, if that works as it
appears, this effect is preserved. If not, this may cause problem if
anyone is building those tools in-tree.

This effect is not preserved for texi2dvi. This may cause problems if
anyone is building texinfo in-tree.

If needed, explicit checks for those tools looking in places relative to
$(top_srcdir)/../ as well as in PATH could be added.

7. The check target doesn't depend on all.

This effect is not preseved. The check target now depends on the all
target.

This concern seems somewhat academic given the current state of the
testsuite.

Also note that this doesn't touch libgloss.
