I blew away the build directory after making sure no builds were running (from the web interface), using

root@servo-master1$ salt 'servo-linux1' cmd.run "rm -r /home/servo/buildbot/slave/linux-nightly/build"

This should work properly the time time it's scheduled on servo-linux1 (I didn't see a way to run a force build on the specific builder to check).
