Changelog:
 - abiv2/fpu.c: Userspace should never be sent NSIGXXX as a si_code.
   Use FPE_FLTUNK instead.
 - abiv2/fpu.c: Use force_sig_fault instead.

I'm hesitant to provide a Reviewed-by: tag for this one, as I don't
understand the signal handling enough myself, and it's something
that should be reviewed properly because of the ABI implications.

Maybe someone else can have a closer look at this?
