The ARM nommu internal toolchain needs some work, similar to the
patchset i've sent for blackfin fixes.
For starters the tuple is wrong, it should be *-uclinux-* (instead of
*-linux-*) in package/Makefile.in
And there are other details regarding uclibc configuration for example
to fix.
It would probably be a good idea to add M-series and R-series cortex cpu
definitions too since those are the most likely to be used for nommu.
I'm looking into it but i make no promises, i lack hardware to test this
and qemu doesn't emulate anything useful regarding it.
