Sam, is this as busted as > I think it is? I really cannot see why it makes a difference. If you use += (and :=) make will resolve EXTRA_CFLAGS when it see it. Whereas with = make will resolve it only when actually referenced. But the way we use EXTRA_CFLAGS it should not matter. If the fix above really helps nfs I need to take a closer look tomorrow.
