My cross-platform Makefile does that:

.c.o:
         $(CC) $(CFLAGS) -fPIC -o $@ -c $<

.o.so:
         $(CC) -bundle -flat_namespace -undefined suppress -o $@ $<      \
         || $(CC) -shared -o $@ $<


Specifically, note the

	
	-bundle -flat_namespace -undefined suppress

also, CFLAGS has -fno-common

Works perfectly on Mac OS X with R12B1
