Avoid a recursive make to speed things up a bit.
A ft32-elf build shows installed objects & libs produce same code.
Mention of ft32-elf-common.ld is dropped as it has never existed
in the tree, and has been an (ignored) error in the past.

A fr30-elf build shows installed objects & libs produce same code.
A lot of code seems like it hasn't been migrated, but that's because
it's all disabled/unused (i.e. all the test & mon code). It looks
like a lot of copy & paste holdovers from the original port.

A i386-elf build shows installed objects & libs produce same code other
than a rename from cygmon-gmon.o & cygmon-salib.o to i386_libcygmon_a-*.o
due to the use of custom CPPFLAGS in here.
Commit 8d75828378 ("libgloss: merge
sparc configure script up a level") missed including the sparc
acinclude.m4 file which meant none of the sparc-specific vars were
propagating to the sub-makefile.
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.
Now that we use AC_NO_EXECUTABLES, and we require a recent version of
autoconf, we don't need to define our own copies of these macros. So
switch to the standard AC_PROG_CC.
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.
We don't want libgloss building against C library headers that happened
to be installed with the toolchain, so add -nostdinc to the build. We
still need access to the compiler internal headers, so probe those and
include them via -isystem. This uses a similar probing style as glibc,
which has used it for over a decade, so it should be safe & stable.
This should prevent any latent bugs due to testing with a toolchain that
is fully configured & installed already.
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.
