Can you run these two commands, each with the symlink set to the different
directories, and post the output?

$ gnuradio-config-info --prefix
$ gnuradio-config-info --sysconfdir

Running with multiple versions of GNU Radio installed the way you are
describing works, but may involve more than just using the symlink.  Here
is an FAQ entry describing one way to do it:
