there is sockets and netdb.h mandated by susv4 which exposes a somewhat
sane interface (now, since gethostby{name,addr} and h_errno are gone).

you can already turn off ipv6 or ipv4+6 or the whole networking (socket+ip).
Socket+ipv6 only would be nice but would mean touching the resolver --
which could need a rewrite anyway (TM).

Not too fancy for the pile it is, but the proper thing to do for a
rewrite, yep. Ok, so let's not hide that odd __dn_skipname (sic) behind
another config symbol for now, just put it in it's own file.
