Did minetest have any ifdefs to build _without_ ipv6 ?

@All

Tried to build minetest on some exotic platform that has no ipv6 support, but only ipv4. And so the question is: is there are some flags or ifdefs, or so in the code so I can simply disable building with ipv6, or, I need hack-and-slash ipv6 related code from?

Thanks.
