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

Use the same CFLAGS as currently in debian 12 (taken from dpkg-buildflags --status). (This might also be the reason why resulting binaries got bigger with newer debian releases.)
