This makes it possible to run tests that need access to installation directories, such as the rundir, without having access to the actual installation directories (/var/run is generally not world-writable), by setting environment variables. This is not a good way to do things in general--usually it would be better to choose the correct directories at configure time--so for now this is undocumented.
