Subject: [PATCH] firmware/Makefile: force recompilation if makefile changes

If you modify the target asm we currently do not force the
recompilation of the firmware files. The target asm is in
the firmware/Makefile, peg this file as a dependency to
require re-compilation of firmware targets when the asm
changes.

Greg,

This was part of the linker table series [0], but I'm going to split up
patches further there. This is an atomic change which is independent
so sending this separately now.
