Subject: [PATCH 2/2] Fix QT4 moc, cflags libs detection on dual QT3/Qt4 systems

On system with QT3 and QT4 qmake in PATH may be from QT3. So we use
pkg-config for proper QT4 detection.
By reqesting cflags and libs for either QtCore, QtGui and QtSupport include
dirs and libs get listed several times, but so we won't mis anything
