Description Kai Dietrich 2012-04-17 04:54:42 UTC

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-strip... /usr/x86_64-pc-linux-gnu/bin/strip

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

Skip that, you included it in the tarball.

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.
