I agree. It's definitely necessary that the build is complete at any
point in time.

I'm reluctantly willing to accept that the build fails with an
appropriate error message until the build system is able to build
everything if we opt for commiting a patchset for simplicity. What's
off-limits is if build "succeeds", but is incomplete due to missing
steps in the implementation. I'm not going to want to guess which part
is already built or which isn't.

Given that the rewrite is a singularity anyways it doesn't really matter
that we will not be able to bisect problems caused by the build system
across the boundary.
