Allow overriding EXPECT

While investigating possible race conditions in the GCC testsuites
caused by bufferization issues, I wanted to investigate workarounds
similar to GDB's READ1 [1], and I noticed it was not always possible
to override EXPECT when running 'make check'.

This patch adds the missing support in various Makefiles.

I was not able to test the patch for all the libraries updated here,
but I confirmed it works as intended/needed for libstdc++.

libatomic, libitm, libgomp already work as intended because their
Makefiles do not have:
MAKEOVERRIDES=

Tested on (native) aarch64-linux-gnu, confirmed the patch introduces
the behaviour I want in gcc, g++, gfortran and libstdc++.

I updated (but could not test) libgm2, libphobos, libquadmath and
libssp for consistency since their Makefiles have MAKEOVERRIDES=

libffi, libgo, libsanitizer seem to need a similar update, but they
are imported from their respective upstream repo, so should not be
patched here.

Automake and GNU Make both use the endif keyword, which conflicts and
elicits an error for matching if/ifdef and endif.

This patch changes the conditional include to use "-include" to prevent
a warning about a possible empty tmake_file.

aix: Add GCC64 configuration and FAT target libraries.

This patch adds the ability to configure GCC on AIX to build as a
64 bit application and to build target libraries "FAT" libraries in both
32 bit and 64 bit mode.

The patch adds makefile fragment hooks to target libraries that allows
them to include target-specific rules.  The target specific rules for
AIX place both 32 bit and 64 bit objects and shared objects
in archives at the top-level, not multilib subdirectories.  The
multilibs are built in subdirectories, but must be combined during the
last parts of the target library build process.  Because of the way
that GCC bootstrap works, the libraries must be combined during the
multiple stages of GCC bootstrap, not solely when installed in the
final destination, so the libraries are correct at the end of
each target library build stage, not solely an install recipe.
