The non-reentrant gethostbyXXXX() functions deadlock if called recursively, for
example if libldap needs to be initialized from within gethostbyXXXX() (which
actually happens if nss_ldap is used for hostname resolution and earlier
modules can't resolve the local host name), so use the reentrant versions of
the functions, even if we're not being compiled for use in libldap_r
Resolves: #179730
