audio/audacity: fix build on non-x86

[pkubaj]

Summary

Audacity by default adds --enable-sse on all architectures, which breaks anything but i386 and amd64. Add SSE option to every architecture, but still enable by default only on amd64 and i386. This will add --disable-sse to CONFIGURE_ARGS, which fixes build.

Looks good to me. Maybe you should think of also marking that option broken on on non x86ish archs.

There doesn't seem to be a way to an option as broken on everything but two architectures (except for several BROKEN entries, each one for each architecture) so I'm leaving it as is.
