I've cherry-picked 3 patches from there onto master locally and I'm
currently running diffoscope to see how that goes (and it's taking
ages…):

I suppose your time is better spent actually working on kfreebsd so
that's why I decided to cherry-pick the patches myself.

FWIW, I'm not exactly entirely convinced by the exporting of the
SOURCE_DATE_EPOCH variable from debian/rules; all other variables have
been passed without exporting so I'm wondering if we shouldn't adapt
this to behave like other variables, reducing possible surprise for
users.

I don't think that's a showstopper for a push to master though; just
thinking out loud.

Sure thing, thanks again!
