The problem was that certain cases tested for __alpha__ and some
__alpha --- same with __sparc.
I think I might have gotten started with the these spinlock changes
because of an __alpha fix. I also verified with an alpha guy that we
need both in most cases, if not all. I remember trying to go with
__alpha__ and finding someone couldn't compile alpha after that.
