Well... that was suttle.

So yes, your patch may certainly be useful to a couple cases, and it 
works fine for this lib1func.S.

It doesn't help me much in the following situation though.  What I 
actually want to achieve is to compile arch/arm/boot/compressed/fdt_rw.o 
from scripts/dtc/libfdt/fdt_rw.c, however I want it to include my local 
version of libfdt_env.h rather than scripts/dtc/libfdt/libfdt_env.h.  I 
still haven't found a way to convince gcc to do that.
