When configuring with -static for a cross-compile to a device it will end up having the wrong path for QT_INSTALL_QML

When configuring with -static for a cross-compile to a device it will end up having the wrong path for QT_INSTALL_QML. The correct path should be including the sysroot. QT_INSTALL_LIBS/_BINS is correct but _QML is not. This causes a problem with the qmlimportscanner calls in qt.prf because it depends on this path being correct in order to find the location of the dependent QML plugins.
