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.
