As explained in the other email, it made failed link test return $? 0
anyway. This broke the stage 1 libgcc configure tests.

Reverting to an older version of gcc and then using it to build 4.9.2-1
succeeded. I also used 4.9.2-1 to build a copy of itself as test, seems
like it works. The only real change was changing atexit use to
__cxa_atexit in libgcc.

Corinna mentioned some problems with gcc misoptimizing atexit over IRC.
