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.
