Just to provide an update on this: the branch dom/reproducible_builds
(with the heavy lifting all done by Niko) is ready to close this bug
with passing tests, but yesterday and today we got some feedback from
upstream about preferring the other patch[1].

Niko, do you have any preferences? I guess the main difference is
that the first version keeps on saying 'Compiled at' even when it's
not actually the compile date. This is probably acceptable for now, though.

Cheers,
Dominic.
