	I am doing a test build now, but that looks good.
Is now the time to include CPU-specific suggestions:

         macx {
             # Auto-inlining causes some Qt moc methods to go missing
             QMAKE_CXXFLAGS_RELEASE += -fno-inline-functions

             # Use PowerPC (not IBM RS/6000) instructions,
             # and pipes instead of temp. files
             QMAKE_CXXFLAGS_RELEASE += -mpowerpc-gfxopt -pipe

             # CPU specific compilation:
             #QMAKE_CXX_FLAGS_RELEASE = -fast -fno-inline-functions
             #
             # -fast defaults to  G5.
             # Add -mcpu=7450 for G4,
             # or  -mcpu=750  for G3 processors
         }

(note that libav* has its own world, so maybe all these
  should be in your new configure-derived universe?)
