Found a new phonon (in 'unstable'), and I think kde-4.4 should be able to link with it.

I updated gstreamer too, because this phonon was not finding a header file. As that
did not fix much the phonon build, I helped the generic builder with NIX_CFLAGS_COMPILER for
phonon to find the proper header files. Either the phonon cmake scripts don't find properly
the gstreamer plugins header file, or we install gstreamer in a strange way.
