sparc64 works
alpha also works
can't test macppc for a while more, but it also looks good.

Here's a proposal for implementing cpu_rnd_messybits() as a read of
the cycle counter on alpha, powerpc, and sparc64. Since I don't have
those archs, the diff is not even compile-tested.
* alpha: RPCC is a 32-bit counter (in a 64-bit register)
* powerpc: TB is a 64-bit counter split into two
