[Reproducible-builds] automated diffoscope for parallel build bugs

[Chris Lamb]

> I propose that one of the builds disable parallelism entirely

So, just to be 100% clear, simply varying DEB_BUILD_OPTIONS="parallel=X"
would not have discovered this gedit bug? (Related, our list of variations
between the builds can be viewed online[0])

Ah, so this is mostly a one-off to justify that you would not break too
many things before you enable it…? If so, I can think of a few hacky and
temporary solutions.

(Can you also clarify what you are saying would be arduous about "manually"
diffoscoping? If the package is reproducible, then diffoscope would clearly
return nothing…)
