A patch

Sorry for introducing these fails. Here is the patch.

I've tested the patch with cross-compler and all the fails disappeared, but I
don't have a powerpc to do full bootstrap & regtest (I'm still applying for gcc
farm account).

I'll send out the patch after I can access gcc farm for a power machine, or
hopefully someone can help testing the patch.

I suppose s390 has similar issue and I will update that accordingly.
