Thanks!

The cfarm machine gcc50 has a 600 Mhz XScale-80219 with 512 MB of RAM,
gcc-4.3.2 release C only bootstrap took 17 hours (and about the same for make
check) - feel free to ask for an account if it's faster than what you have.

If you know a way to purchase qualcomm snapdragon dual core 1.5 GHz arm (or a
contact that might lead to it) I'm interested :).
