<h3>Log Message</h3>
<pre>mp-buildbot: Don't re-run previously failed builds
If a port's build has previously failed, we do not want to waste cycles
to re-attempt it (e.g. as dependencies of other ports), unless the
failed port's definition has changed.
To achieve that, create a file with a reference to the last failed build
for every failing port, and fail builds that depend on failed ports
early.</pre>
