Here's another thought. You could build a multilib cross-compiler for
the final system binutils and gcc with the host of
powerpc-unknown-linux-gnu and the target of powerpc64-unknown-linux-gnu.
Then use a config.site to force everything to powerpc-unknown-linux-gnu
instead of the uname hack. That would probably make upgrading the kernel
loads easier. Or even maybe just building a completely 32bit userspace
and build a 64bit binutils, gcc into /opt specifically for compiling the
kernel.

Just some food for thought.
