Subject: 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.
