r72111 <http://trac.webkit.org/r72111> added a custom buildbot scheduler that avoids triggering builds for changes that only touch "other-port" files.
This scheduler is currently used by the all the Apple bots (both OSX and Win): grep for PlatformSpecificScheduler on file Tools/BuildSlaveSupport/build.webkit.org-config/config.json
I think that we should (if needed) patch this scheduler to work also on GTK and switch the GTK bots to it.
General documentation about the buildbot schedulers can be found here: http://docs.buildbot.net/0.8.8/manual/cfg-schedulers.html
