[Qt-creator] Debugging as super-user

[Bryce Schober]

Neither option works for me. Our application, which is a PC-build-variant of
our embedded application, calls mlockall(), which fails with EPERM. Normal
command-line usage of sudo works great, either for running or debugging with
gdb, but I'm not sure how I would get equivalent permissions through
qt-creator.
