The other trick I can recommend is to write a GNUmakefile containing:

ARCH=foo
CROSS_COMPILE=foo-linux-
include Makefile

(GNU make reads GNUmakefile in preference to Makefile.)
But this manual hackery is still not nearly as nice as the automagic way.

I'm not sure I follow exactly what your concern is.  I am mostly familiar
with doing x86 and powerpc builds.  For both of those, the kernel config
sets whether it's the 32-bit or 64-bit world.

Thanks,
Roland
