Changed win_gui cross compilation to use cleaner Qt setup

A separate cross compiler mkspecs file (win32-x-g++) is now used to
configure all build options so the setup-mingw-cross-compiling hack is
not needed anymore. Furthermore, the MinGW setup is now on path, so no
need to specify extra PATH changes for it.
