Good call, I missed that. Of course it makes much more sense to build on a
fast FX box with -j8, but have CFLAGs for the X2, which according to the
safe cflags wiki (
http://en.gentoo-wiki.com/wiki/Safe_Cflags/AMD#Athlon_64_X2) is:
CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=k8 -O2 -pipe"
CXXFLAGS="${CFLAGS}"
