busybox: make sure architecture flags are used at link time
When compiling Busybox, according to readelf -A, all object files were properly compiled according to the select architecture (-march=armv4t for example), but the final busybox binary could be of a different architecture (ARMv5t even if ARMv4t was selected). This patch changes the way we configure/compile Busybox so that our CFLAGS aren't anymore passed through the make EXTRA_CFLAGS variable, but through the .config CONFIG_EXTRA_CFLAGS variable. Unfortunately, those variables don't have exactly the same semantic for the Busybox build system. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
