Apart from that in the Makefile you have to specify with
ARCH ?= ppc
and in CROSS_COMPILE the prefix of your cross compiler (e.g. pcc-linux-)

beware that the corss compile toolchain is in you $PATH.

If you want to cross compile for an embedded Linux board, have a look at 
buildroot. With this tool you can build the whole userspace environment 
to get a shell running.

good luck,
matthias
