The documented way to do this is to just set the link-local address in
ifconfig_IF_ipv6, since an interface is required to have a link-local
address. Either configure an fe80:: address explicitly or set

    ifconfig_em0_ipv6="inet6 auto_linklocal"

Alternatively, if you set ipv6_activate_all_interfaces all interfaces
will be considered IPv6-capable.
