linux loses out on the Libc(bcopy) score because gnu libc doesn't have
ppc-optimised string and memory operations. This really surprised me,
but hopefully someone (maybe me, if i can learn ppc assembly fast
enough :> ) will implement them.
The other memory bandwidth and latency numbers are too close to call,
unless i'm missing something.
