Details:

When LDFLAGS is set to "-Wl,--as-needed -Wl,--no-undefined", gnustep-gui
0.14.0 produces a lot of undefined refereces, such as:
obj/NSDocument.o: In function `-[NSDocument makeWindowControllers]':
/home/fwang/gnustep-gui/BUILD/gnustep-gui-0.14.0/Source/NSDocument.m:371:

more undefined references to `objc_msg_lookup' follow

Maybe some more -l libs should be used?
