[coreboot] [PATCH] v3: remove duplicated/unused Makefile rules

I see you're testing on qemu.

I think that for all those patches I've seen these last two days, if
tested on qemu, you can use this ack.

The patches you are submitting represent substantial improvements, we
need them, we'll make them work. I will try to test later today but my
workroom is now occupied by a guest, so I have to drag stuff out of
there to test.
