​I think this is right, but as I said, it's been ages since I've done this
without linkage-tables. And when I did, everything was shared via NFS, so I
didn't have to move things around.

However, I do remember that if the C code was recompiled and caused things
to move, I had to do a new genesis to get the addresses corrected.​

​I think cross-build-world.sh without -c should be enough so you don't have
to recompile everything. You just need to run genesis again.
