arch-armv4: Allow -march=armv4
Even though it is deprecated in GCC 6 [1] it has not yet been removed from gcc upstream. We do have active machines in OE ecosystem which use armv4 ( SA11xx ) e.g. collie in meta-handheld so until upstream gcc takes next step to remove them lets support armv4 again, we are still carrying the relevant gcc patch to support v4 BX fix.
