Set FEF bit in the %fprs register when handling an fp_disabled trap from
userland. Prevents userland applications from trapping forever on the next
floating point instruction executed after clearing this flag. Fixes issues
with threaded applications, sinc our pthreads library clears the FEF bit
under some circumstances.
