I stand by my opinion that Thomas' patch is a kluge rather than something
we should accept as a long-term answer.  However, in the interests of
keeping the buildfarm green, maybe we should commit it until we have a
better solution.  It looks like seawasp is only building HEAD, so I think
we could commit this in HEAD only.
