The reason I was doubtful about the right thing to do is that kernel
and kexts aren't supposed to be using floating point at all, and
-msoft-float is just used to prevent float reg refs from getting in
by accident.  What I think kernel folks would most like is a libgcc
where adddf3 etc is not defined at all, so that mistaken references
show up as a link error, but that's a pretty unusual variant of
multilib.
