[Bug libstdc++/43203] New: abi_check from libstdc++ tests fails with CFLAGS="-march=core2"

[4ernov at gmail dot com]

I've tried to built gcc-4.4.3 with different CFLAGS and CXXFLAGS variable and
have found that when they are "-march=core2" there's one unexpected failure in
libstdc++ tests: FAIL: abi_check. Everything else in test results is equal. I
know that I should build gcc with neither CFLAGS nor CXXFLAGS set but maybe
it's some kind of useful information.
