In reading getent(3) for HP-UX 11.11
  http://docs.hp.com/en/B2355-60103/gethostent.3N.html

that gethostbyname_r(3) and gethostbyaddr_r(3) are categorized
as obsolete interfaces, and hence moved from -lc to -ld4r and
may be completely removed in subsequent releases.

It would seem that it not appropriate to add detection
for -ld4r and these obsolete interfaces.  Instead, the
code should use gethostbyname(3) and gethostbyaddr(3).
Unforunately, these will be unnecessary mutex protected
in -lldap_r as we have no good way of detecting whether
or not their implementations are thread-safe.
