Bug ID: 51734
           Summary: Add a FreeBSD build VM
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86
                OS: NetBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: [e-mail]

        Depends on: 47903

Similar to bug #47903, but FreeBSD generally works with Wine :)

There have been several patches in recent months to fix breakages related to
the FreeBSD port that ideally would've been found by the testbot preemptively
rather than after the fact (e.g.,
https://source.winehq.org/patches/data/213680).

A test VM would also be welcome, but a build only VM would be a very helpful
first step.
