[Mingw-cross-env-list] Static GStreamer plugins aren't loaded

[Nikos Chantziaras]

I can't figure out how to link against a static GStreamer.  If I just do:

  PKGCONFIG += gstreamer-0.10

in my qmake project file, no plugins are loaded and thus no media can be 
played at all.  I've also tried to add all *.pc basenames (like 
gstreamer-base-0.10, gstreamer-audio-0.10, etc.), but still no joy.

Any hints on how this is supposed to work?
