We don't have this at the moment, so I'm not sure we need to
add it as part of moving to doing merge testing via gitlab ?
The current process is "if the pullreq causes a test to fail
then the pullreq needs to be changed, perhaps by adding a
patch which disables the test on a particular platform if
necessary". Making that smoother might be nice, but I would
be a little wary about adding requirements to the move-to-gitlab
that don't absolutely need to be there.
