Good question!

Original commit: http://hg.nginx.org/nginx/rev/a6d116645c51

The configure option `--with-ipv6' isn't avaliable anymore, so it's been removed
from nginx-devel/Makefile too.

According to nginx-1.12.0/auto/unix, the nginx tests the IPv6 feature this way:

# RFC 3542 way to get IPv6 datagram destination address

ngx_feature="IPV6_RECVPKTINFO"
ngx_feature_name="NGX_HAVE_IPV6_RECVPKTINFO"
ngx_feature_run=no
ngx_feature_incs="#include <sys/socket.h>
                  #include <netinet/in.h>"
ngx_feature_path=
ngx_feature_libs=
ngx_feature_test="setsockopt(0, IPPROTO_IPV6, IPV6_RECVPKTINFO, NULL, 0)"
. auto/feature

A GENERIC kernel contains the INET6 option and both header files are available,
so, on default FreeBSD installation compiles an nginx with IPv6 support
by default.
