+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).
