You don't say what your target OS is or what libc you're using. Busybox
is targetted at Linux with glibc or uClibc and that's what it's mostly
tested on. The processor shouldn't matter (mostly) as long as as there's
a gcc for it, which yours clearly has.  There is some support for other
OSes and libcs, but you'll find that not all applets will compile.
