Sure, but why do we even need to build the modules in the host version
to begin with?
We should probably build the host version with --with-platform=none I
think.
Yes, we do currently use cdboot.img from the host, but that is probably
a mistake and a remnant for long ago... Instead, I think we should only
used modules from the target build.
