Note that Maxime already reported this problem three months ago:

Except for the environment, I don't expect we'll see much interesting
Probably more useful are all the config.log under output/toolchain/gcc*
(especially output/toolchain/gcc-*-final/*/libgcc/config.log and config.h)
I vaguely remember having looked at this or a similar problem, and
coming to the conclusion that there are some files that gcc builds
a few files in libgcc with the host's config.h instead of the target's.
And if I remember correctly, this was still the same in gcc 4.7 and
upstream git. Rainer, you reported that it works with gcc 4.5; can you
check if it is still broken in gcc 4.7?
It would be interesting to diff the config.log results between 4.5 and
4.6. So maybe, put a tarball of the whole output dir with a 4.5 and a
4.6 build in a pastebin...

Did you try it on an i386 machine?
