Tests Failing On x86_64

[nick]

Greetings all,

I am getting failing tests when running with:
make bootstrap
make -k check

The only code I am running is the below patch:

Subject: [PATCH] Fix bug 86293

This fixes the bug on the gcc bugzilla with id, 86293. Basically
a variable is undefined in certain build configuration scentarios
and therefore must be enabled with the attribute marco and the
flag, unused for it to avoid this build error.

It seems to be failing in Running /home/nick/obdjir/../gcc/libatomic/testsuite/libatomic.c/c.exp ...
as this is the last thing I see but it could be a mistake in my code or something else. It does
build gcc find through so it seems to be tests failing that are not expected. Thoughts?

Cheers,

Nick
