The RCN kernel build scripts (so my scripts as well) will download a
known working linaro cross-compiler if you run on an x86 machine and
don't point the build scripts to a pre-installed tool chain.
Review the scripts/gcc.sh shell script if you need hints on getting the
cross-compiler up and running, but it's pretty straight-forward.
