Hi,

FreeBSD-world defaults to soft float for all MIPS flavors/variants. We actually
patch GCC to assume soft float as well, but it would be most convenient for the
Clang driver to assume soft float for FreeBSD since hard float is actually the
odd-ball out and the needed information is readily available. Patch attached as
an example...

I still do not have a functional test setup, so it's not clear to me if any of
the applicable tests break when this default changes. I'll work on that,
though...
