From: Tom I Helbekkmo <tih@Hamartun.Priv.NO>
Apart from this Makefile hack, all I've done is to make dynamicallyloaded code modules fail properly (as was already done for __mips__,although I think this is too loose: I believe NetBSD for the pmax cando dynamic linking), and to add test-and-set lock handling. As Brucesuggested, this is done in a maximally efficient inlined way: I wasnot aware that this code was so important, speed-wise.
