Buildbot changes to allow out-of-tree builds (#11180)
* Do proper out-of-tree builds with buildbot * Don't write to bin/ for cross builds * This allows safely building multiple builds from the same source dir, e.g. with the buildbot. * Disable Gettext (by default) and Freetype (entirely) for server builds
