Makefile: make it cross-compile (and Buildroot) friendly.

The current Makefile makes heavy assumptions that it is doing native
compilation on the RPi, as it checks that `uname -m` is an ARM machine.

This is wrong in the cross-compilation case.

Remove the conditional altogether, and do not override the CFLAGS
as passed in the environment (Buildroot passes proper CFLAGS).
