The libgloss port has been reaching back into newlib internals for a
single header whose contents have been frozen for almost a decade.
To break this backwards libgloss->newlib dependency, move the acle
header to the srcroot include/ so everyone can use the same copy.
A recent change to the Makefile.in for riscv resulted in the
machine/syscall.h header not being installed. This updates the file
to install this file again.

PR 29515 points out our documentation builds are broken, let's just move
over to the new non-recursive builds.

Avoid a recursive make to speed things up a bit.
This drops the header install logic because the lm32/ subdir doesn't
actually have any header files to install.
Now that we require Automake 1.15, we can use this macro rather than
set the tool up ourselves. The current code doesn't properly search
for a prefixed ar tool as-is.
When merging iq2000 up a level, it included a partial conversion to
AM_PROG_AS in the common directory. Finish it for all directories
to kill off the custom LIB_AM_PROG_AS which we no longer need since
we require Automake 1.15 now.
Use AM_MAINTAINER_MODE so devs have to opt-in to automatic rebuilds
of autotools. This matches what newlib (and most every other GNU
toolchain package) does with automake.
Move the minor wince-specific logic to a dedicated file & namespace
them so we can merge its configure logic up a level. The makefile
is a bit tricky, but maybe it still works.
Move the minor mn10300-specific logic to a dedicated file & namespace
them so we can merge its configure logic up a level. part_specific_obj
wasn't used anywhere (looks like copy & paste left over from mips), so
drop it entirely.
The mn10200-specific logic (setting up part_specific_obj) isn't used
by the build anywhere -- looks like copy & paste left overs from mips.
So punt that & merge the target_makefile_frag_path up to the top-level.
This is used in a bunch of places, but nowhere is it ever set, and
nowhere can I find any documentation, nor can I find any other project
using it. So delete the flags to simplify.
Compiling the basiccrt .S files missed an include to the local bfin/
headers causing the build to break when installing anew.

The top level dir isn't doing anything interesting, just recursing into
subdirs. So this change isn't terribly exciting. But it sets us up for
doing more fun stuff in follow up commits.
[TODO] Check test targets
The toplevel makefile used by binutils/gcc/newlib/etc has install-pdf and
install-html targets, but they fail because libgloss doesn't support them.
Tested with an arm-eabi combined tree build and install, and verifying that
the install-pdf and install-html targets now work, and that the pdf and html
doc files are now in the install tree.
libgloss/
* Makefile.in (install-html, install-pdf): New.
* doc/Makefile.in (htmldir, pdfdir): New.
(porting.ps): Delete white space on blank line.
(install-pdf, install-html): New.
