Use userspace version unless _HARDKERNEL. Otherwise we use atomic 

cas to implement spinlocks and spinlocks to implement atomic cas....
which might suck.

Since the userspace version uses ll/sc, which doesn't exist on
R2000/R3000, rump will not work on those platforms.  *snif* (well,
pthread in general AFAICT).
