Erm, specifying a minimum support CPU in the package description is
not acceptable IMHO. The fix here is to patch the packages buildsystem,
so that it gets build for the minimum cpu level which is supported by
Fedora, and thus will work out of the box on all systems Fedora
supports.

No tricks / hacks with multiple compilation, cpu detect scripts, etc.
will be necessary then.
