(a) MATH_EMULATE is slow.
(b) Keeping all the overhead in userland is not as bad.
(c) Serious, you are talking about hardware with limited computation
power -- binary compatibility is not such a big deal for that.

That said, I have to take a look at how much work -msoft-float really
is. I would be willing to fix it.
