On a gentoo hardened system, the compile of sys-devel/gcc-4.4.6-r1 fails during the configure phase. Here is a short snippet of the build log: checking for x86_64-pc-linux-gnu-ranlib... /usr/x86_64-pc-linux-gnu/bin/ranlib checking for x86_64-pc-linux-gnu-strip... /usr/x86_64-pc-linux-gnu/bin/strip checking whether ln -s works... yes checking for x86_64-pc-linux-gnu-gcc... /var/tmp/portage/sys-devel/gcc-4.4.6-r1/work/build/./gcc/xgcc -B/var/tmp/portage/sys-devel/gcc-4.4.6-r1/work/build/./gcc/ -B/usr/x86_64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -isystem /usr/x86_64-pc-linux-gnu/sys-include checking for suffix of object files... configure: error: in `/var/tmp/portage/sys-devel/gcc-4.4.6-r1/work/build/x86_64-pc-linux-gnu/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[2]: *** [configure-stage1-target-libgcc] Error 1 Reproducible: Always Steps to Reproduce: 1. emerge -uDNv world 2. wait for gcc build to fail

You are using a newer gcc which understands -march=atom to build an older gcc which does not, so you need to stick to something like -march/-mtune=i686 in your CFLAGS.
