It assumes that one is using an optimized userland for 4xx.  This
means that the expectation is that you have soft-float binaries.
Most people are using ELDK or MVL.

instruction trap if floating point instructions were being
attempted with no emulator code present.

Good point.  Maybe we should add in an illegal instruction warning
on the no mathemu path in the 4xx program check exception.
