The more I looked at that patch, the more holes I could see in what we
were doing (and what Angstrom currently does). I started playing around
with the patch below which tried to improve on that idea.

I then concluded that we might be able to do something like:

MACHINEOVERRIDES := "${MACHINE}"
MACHINE_append = "-uclibc"

since what we're really trying to do in the uclibc case is replace
anything MACHINE specific with something containing uclibc?

Thoughts?

Cheers,

Richard
