...to manually build solver/*/bin/test-passive.oxt via "make
Extension_test-passive". There's still room for improvement in gbuild, though:
* There should be no need to add the extension's native library and jar UNO
components (which nothing else links againts) to the central Repository.mk.
* There should be no need to move manifest.xml around.
* There should be no need to move .java files around.
* Let "make Extension_test-passive.clean" clean up again.
