Please attach config.log from one of the failed emerges. Also don't expect anyone to care about your build or runtime failures with those CFLAGS/CXXFLAGS.

We need to see config.log; the build log is not sufficient.

Strangely enough gcc-4.6.3 compiles fine with itself O_0
conftest.c:1:0: sorry, unimplemented: Graphite loop optimizations cannot be used (-fgraphite, -fgraphite-identity, -floop-block, -floop-flatten, -floop-interchange, -floop-strip-mine, -floop-parallelize-all, and -ftree-loop-linear) So it seems that you are trying to use graphite on a gcc that was compiled with USE="-graphite" Reduce your compiler flags to sane values or enable the graphite flag. Reopen this bug if the problem still exists then.

I never used graphite on both of my systems! And even after recompiling gcc-4.6.3 with itself everything fails with the same error :(

GCC will of course still build with itself, as CFLAGS are entirely ignored while building GCC.
