This MachFPTrap() seems called only if T_FPE occurs in !SOFTFLOAT case
so I guess it will rarely happen, but reverting this seems to fix
"Illegal instruction" error during make install in pkgsrc/lang/pyphon2.6
on R5000 O2. (have not investigated what insn triggers it though)

I'll revert the above line in a few days if there is no objection.
