gnuradio builds without thrift but with ctrlport enabled causing runtime issues

[jacobagilbert]

seems like apache-thrift should be a dependency, or -DENABLE_GR_CTRLPORT=OFF should be a CMAKE arg. Not sure what the desired behavior is.

The original design was to have CTRLPORT be enabled separately from its actual implementation. Reality is that no other front ends have ever been developed, so Thrift ends up bring the de-facto front end. I believe that current Thrift even with patches for building still has runtime issues; been a while since I checked though. CTRLPORT is crufty, and needs an update ... or, to be removed ... or replaced by something different & hopefully better!
