Wow... that's *much* better that I would have guessed. Is the
compiler the same for each?

I wasn't trying to compare fairly, mostly get the lowest possible
compile time.

I don't have a PPC host to reasonably compare with, but a 440GP kernel
(linuxppc_2_4_devel) for me builds in 3 minutes 29s (with gcc-2.95).
