On AIX, shared objects must be wrapped under an archive file. For testso, creating libcgosotest with an extern symbol isn't AIX-friendly. By default, ld will block such behavior. Rather than forcing ld to work as on Linux and using the run-time linking, goCallback became a function pointer which is set by setCallback().
