Oh, neat, I wasn't aware of this feature.
The difference is CFLAGS-elbg.o appends to the normal CFLAGS instead of 
replacing them, but

elbg.o: CFLAGS += -O2

does the same thing indeed, so (unless we care about non-GNU makes and they 
can deal with the patch but not with this) there's no need to apply the 
patch.
