+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
