I'm tempted to call such systems broken. Simply defining the AF_INET6
constant is cheap, and it's really independent of ipv6 support. The
glibc sys/socket.h defines for example AF_X25, AF_IPX, AF_APPLETALK,
AF_ROSE, AF_DECnet, AF_ECONET and a bunch of oter families that I've
never heard of before.

If really needed, we can add an

#ifndef AF_INET6
#define AF_INET6 4711
#endif

somewhere to take care of that.

Anyway, if we want to test for the AF_INET6 constant, AC_TRY_LINK is
also overkill.
