I know nothing about any BSDs, but according the ip(4) man page found on
the Internet, the IP_BINDANY socket option should give you the same
behaviour on FreeBSD as the Linux IP_FREEBIND option.

And this option is used by the BIND9 lib/isc/netmgr/socket.c code in the
socket_freebind() implementation, if it is defined.
