I remember this issue from before. Unfortunately, NetBSD insists on not 
providing a suitable declaration for simple, thread-safe functions. That 
means they are asking us to use the non-thread-safe versions if 
getaddrinfo(3) isn't enough.

In any event, kresolver_p.h checks for the definition as well:
/* some systems have the functions, but don't declare them */
#if defined(HAVE_GETSERVBYNAME_R) && !HAVE_DECL_GETSERVBYNAME_R
extern "C" {
  struct servent;
[...]

Maybe the cmake test is testing only for the symbol presence, but not its 
declaration? We need both in this case.
