[Regression] ./configure looks for mkspecs in the install dir

Not sure if this is done on purpose or not ...

Since commits 28c23cdd08c3d6d9f8440047a15efcd865fa4a8c and 1fe3c3f38701c3af27c5385acfb8458d1b85bfca I have the problem to configure Qt to build without Phonon (QTBUG-12466).

From a previous installation of phonon from git (which I installed after Qt) I still have the file "/local/qt4/mkspecs/modules/qt_phonon.pri" in the install dir, whose contents is "QT_CONFIG *= phonon".

Probably due to the symlinking of mkspec dirs, configure apparently looks into the install dir, finds this module, and I can no longer configure Qt to build without phonon.

I could erase the install dir, too, but as I am used to build into a live running system, this would kill my desktop

Thanks Oswald for your patience...
