From c7259bfc91e1fd5c9db642e59d13dd5b835517cd Mon Sep 17 00:00:00 2001

Subject: Add specialization for i486 that uses -mtune=generic, as Debian
 invokes the build with --cpu=i486 on x86-32.

Add -momit-leaf-frame-pointer to x86 specializations.

Use -march=atom for atom32 as well.

Use -mcpu=cell for Cell PPU - it's not documented, but GCC 4.6 has it.

Remove ancient/untested rs64a support from ppc64
