Since this test would involve building every package at least twice, I
think it wouldn't be possible for most users who would run `make check`.

Right, I think that testing all the packages for reproducibility is best
done by the continuous integration server, whether Hydra or Cuirass. The
CI server can perform the tests on a variety of build farm machines,
record the results, and present them to users somehow.
