Ok, I just backed out the libstdc++ patches which fixed it for now. I am trying a couple different profiledbootstraps. One with just --with-build-config=bootstrap-lto and one with "--enable-clocale=gnu --with-system-zlib --with-demangler-in-ld --enable-languages=c,c++ --enable-gnu-indirect-function --with-fpmath=sse".
