[Qt-creator] Debugging as super-user

[Bryce Schober]

Actually, that doesn't work either. Qt Creator launches my application under
the gdb-su, but it can't communicate for some reason. When I try to pause
the app, it fails to pause, and the debugger window shows:

State changed from InferiorRunning(10) to InferiorStopping(11).
sStop requested...
dTRYING TO INTERRUPT INFERIOR
dCANNOT INTERRUPT 32147

My reference is that if I launch qt creator as root, all the debugging runs
smoothly.
