[packages/ardour] force build with MMX and SSE

[Elan Ruusamäe]

you can enforce runtime probe dependency:

$ grep -r Requires.*cpuinfo ~/all-specs
/home/users/glen/all-specs/adobe-flash.spec:Requires: cpuinfo(sse2)
/home/users/glen/all-specs/google-earth.spec:Requires: cpuinfo(sse2)
/home/users/glen/all-specs/kernel.spec:Requires: cpuinfo(pae)
/home/users/glen/all-specs/ClanLib.spec:%{?with_sse2:Requires: 
cpuinfo(sse2)}

sorry if this is totally out of context.
