firmware/Makefile: don't use distribution's CFLAGS

Set CFLAGS on top of the Makefile, to avoid using the distribution's
default CFLAGS. In debian testing and unstable, -fcf-protection was
recently added to the default CFLAGS, but it cannot be used with the
cross compiler:

  [COMPILING libosmocore/source/backtrace.c]
  cc1: error: '-fcf-protection=full' is not supported for this target
  make[2]: *** [Makefile:270: obj/simtrace/flash_backtrace.o] Error 1
