Changes (by duncan):

  * priority:  normal => low
  * difficulty:  normal => very easy (<1 hour)
  * severity:  normal => minor

Comment:

 For context, GHC rejects the combination of threaded and profiling. Some
 projects specify `ghc-options: -threaded` which means when some other
 developer comes along to profile this executable they bump into the error.

 So perhaps Cabal should just filter out the option when building profiling
 executables and warn that it's doing so, since changing to the single
 threaded rts may have other behavioural effects.
