Support for Athlons depends on the compiler version. gcc-3.2, just
imported to -current, has:

march=athlon|march=athlon-tbird|march=athlon-4|march=athlon-xp
mcpu=athlon|mcpu=athlon-tbird|mcpu=athlon-4|mcpu=athlon-xp|mcpu=athlon-mp

If you're using an older version of gcc (like 2.95), then the Athlon
is not explicitly supported.
