The internal toolchain won't work with Cortex-M3, mostly because of the
fact that some packages (notably: uclibc and glibc) fall back to regular
ARM instructions in some situations, and Cortex-M3 has no support for
those kind of instructions.
So, just disable it for now and rely on the external toolchain.
