That still makes this table a maintainence headache.  Can we instead say that we built on modern/supported-by-upstream releases of popular operating systems and distributions.  And we build test on the platforms supported by our CI system.  See https://gitlab.com/NTPsec/ntpsec/blob/master/.gitlab-ci.yml for the specific platforms that we test on.

Otherwise, we're maintaining data in 2 places and it's going to get out of sync.
