Rob, judging by http://landley.net/notes.html you do a lot of cross-compiling
to different CPU arches and are playing with qemu.

Can you give me an advice what arch(es) is(are) suitable for
building and testing busybox for NOMMU arch.

At least which NOMMU arches
1. Are supported by qemu 0.9.0
2. Have mostly working support in binutils and gcc

Availability of a known working example of qemu image for an arch is a plus,
but isn't critical. If there is no such thing on the net,
I will try to build a kernel for it and make my own.
