4717 # $(PRIVATE_OBJECTS) <-- The .o that we built
4718 # $(PRIVATE_STATIC_LIBRARIES) <-- The .a that we built

4720 # $(PRIVATE_SHARED_LIBRARIES) <-- The .so that we built
4721 # $(PRIVATE_LDLIBS) <-- System .so

4726 # of 'libraries'.

4739 # For now, assume that whole static libraries are not needed.
