OK, I guess we need some better wrapping of compat code.

Yeah, probably for several of the 64 bit arches. Sounds like
a nice little kernel-janitor project.

Um, why is it using the host's gcc? I ran make with
make V=1 ARCH=ppc64 CROSS_COMPILE=/opt/crosstool/powerpc64-unknown-linux-gnu/gcc-3.4.2-glibc-2.3.3/bin/powerpc64-unknown-linux-gnu-
so it really should know better, shouldn't it?


Check out arch/ppc64/boot/Makefile, in particular CROSS32_COMPILE. The
boot wrapper is a 32bit binary.

Now that the toolchain is biarch capable we could get rid of that and
use gcc -m32 instead. But for the moment specify a CROSS32_COMPILE ant
things should link.

Aha! Got it. Thanks!
