There's a tradeoff here. In a minimal GNU/Linux environment coreutils is
there but not openssl. So I don't mind the substitution (for the test
suite), but I think you need to add a
"test_require_external prereq openssl" or equivalent to T530-upgrade.sh

This will also require adding openssl as a debian build dependency; I
can also live with that, although it might inconvenience some people
building the debian-snapshot target.

There's something aesthetically displeasing about hardcoding the
checksum into the test script but I think I'm just grumbling at this
point.
