probably because you have optimized settings in your fortran flags and the gcc ebuilds don't filter those flags
*** Bug 435032 has been marked as a duplicate of this bug. ***
The optimized settings are from arch/x86/make.defaults: CFLAGS="-O2 -march=i686 -pipe" CXXFLAGS="${CFLAGS}" FFLAGS="${CFLAGS}" FCFLAGS="${CFLAGS}"

(In reply to comment #17) i used an x86 chroot if the problem exists for you, please try the patch and report back
well, no one responded, so i'll just assume it fixes things http://sources.gentoo.org/eclass/toolchain.eclass?r1=1.553&r2=1.554
