Hmm, the patch only brings the behaviour with the internal assembler
in line with the external assembler, which is still the default on
PowerPC, so bots wouldn't see any difference.

On the other hand, I guess on *Intel* the internal assembler is now
the default, so the patch would change behaviour there, right?

I can certainly run a GDB testsuite regression on Intel before
checking this in.

Thanks for the review!
