What about the build log itself ? The other will be useful only after we know which one of those config.logs should be checked.

Well, one chance is that '-mmmx -msse -msse2 -msse4a -m3dnow' shouldn't be in your CFLAGS (looks bad regardless), the other - that you've failed to set 32bit emulation (or whatever that option is called) in the kernel.

checking whether the C compiler works... configure: error: in `/var/tmp/portage/sys-devel/gcc-4.7.2/work/build/x86_64-pc-linux-gnu/32/libquadmath':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
checking for backtrace_symbols... yes
checking for gettimeofday... make[1]: *** [configure-target-libquadmath] Error 1
make[1]: *** Waiting for unfinished jobs....

[Comment 8 SpanKY 2012-10-08 19:48:39 UTC]

yes, you need to have x86 support in the kernel in order to build a multilib gcc
