Does this mean you have some kind of patch for this stuff? Even if
it's pretty raw, it should save me/riku some time on knocking up a
multiarch package to test with. And it would help me grok some of
what's been discussed.

Anything that installs and allows $stuff to install build-deps (and
hopefully even build) is a major step forward even if there are plenty
of remaining wrinkles.

Thanks everso for looking into this.
