Summary

Drop a clause that's no longer relevant to v4/v5. Drop support for
softfloat for v[45]. Simplify soft float expression by assuming we're
always either armv6 or armv7.

Do we still support softfp v6/v7?

Yes. We support it as a CPU variation via CPUTYPE.

It's either a 'hardfp instructions, passed around in int registers' or 'software fp, in int registers'. We have the former in tree. I believe we also have the latter, but Juniper wanted this for a core they were exploring so we added it. I've not tested it in some time, however.
