I tried the above, and it didn't even try to compile \
arch/arm/boot/compressed/inflate.o The definitions in scripts/Makefile.build seem \
pretty straightforward, but they don't seem to get invoked as I expect.

I finally gave up (for now), and set CONFIG_MODVERSIONS=n so I could
get to some testing.  As you can see from the build output below, this
fixes the .tmp_inflate.o problem, but now on ARM I get an unresolved
external.  Any ideas?
