We don't even need a separate buildbot. Just a relatively simple
improvement to the existing buildbot.

See:
    https://trac.macports.org/ticket/52742

I suggested adding a field to allow manually specifying arbitrary
values for variants. But we would need some automatism as well.
Perhaps something like the following:

    If variant quartz exists, build the port once again, but this time
with '+quartz'

but covering all corner cases (when +x11 +quartz is allowed together
and when it is not ...).
