Comment (by iay):

 Fixing the `+gssex` variant patch is out of my league, so I looked into
 fixing the much simpler compilation issue on 8.4p1. That turns out to be
 relatively easy to fix, although given what I did to make it work I have
 to say I don't understand why the same problem doesn't appear to come up
 with 8.6p1. However, that's a relatively uncontentious patch so I will
 make a PR for 8.4p1 and hopefully that can take us forward.

 I also looked into the test failure issue. This seems to be down to
 failures in the sandbox that `sshd` is run in failing to initialise. It
 fails for one reason if there is no `openssh` port installed already (it
 references a file that is installed by the port itself, which I'd say was
 a no-no), and in a different way (operation not permitted) if one is. The
 latter case may be macOS version related, as I'm on Big Sur. I guess
 that's a separate ticket though, and again I'm not sure that I have the
 knowledge to move it forward. It may also be something that affects the
 upstream, as the upstream `sandbox-darwin.c` doesn't seem to have changed
 recently.
