Ah, so there isn't a direct way I'm not aware of, you still bind to a specific ip address (or multiple), just specified in a different way ;) Note that supporting this isn't going to work with a single listening socket. Having ipv6 sockets accept ipv4 connects too works for wildcard sockets only. If you want listening on all ip{v4,v6} addresses of an interface you'll need a listening socket for each.
