Ah. that's the piece I was missing: the CI is using an unmodified,
released version of Buildroot. That's neat! :-)

I can see the chicken-n-egg problem, now, thanks.

I've reinistated these pactches in the "new" state, so they are back
under consideration. We'll see what the opinion of the other maintainers
are.

Peter, Thomas, Arnout: your thoughts?
