Several changes:
- We only allow generate header "inside" the tree. Why? Because we
need to connit the result, so it makes no sense to generate them on
the build dir.
- We only generate a single target each time. Getting all the
cross-compilers correctly is an impossible task. So know you do:
make -C tests/migration $target (native)
make CROSS_PREFIX=foo- -C tests/migratiion $target (cross)
And you are done.
- If we are building out of tree, we have no data about if we are
cross-compile or whatever. So instead of guess what is happening,
just do what I pointed on previous point.
