I don't think we're there yet. libkvm is not ready for generic
cross building and we don't really have the infrastructure for
it either. For one, we really need to install CPU-specific
headers on the host.

We can manually cross-build a few things, like binutils and gdb
and I see value to extend that to kgdb, but that's about it.
