Well they are reasonable as build machines. Having enough ram is
important.
Still compared to a 3.7GHz 6 core 64bit IBM powerpc, they are not fast.

Yeah I never did like freescale's build methods. It's a mess.
Well if there are enough people actually using them I hope the port can
find the developers it needs to keep going. I don't see much future in
the architecture as far as new CPUs is concerned. Making regular powerpc
designs just seems to make a lot more sense.
