+	* nss/Makefile (databases): Add key and rpc only if sunrpc appears in
+	the $(subdirs) list.
+	(CPPFLAGS-getent.c): New variable.  Pass -D option to set HAVE_SUNRPC
+	to 0 or 1, indicating whether sunrpc appears in the $(subdirs) list.
+	* nss/getent.c (print_rpc, rpc_keys): Conditionalize on [HAVE_SUNRPC].
+	(databases): Conditionalize rpc entry on [HAVE_SUNRPC].
+
 	* elf/Makefile (routines): Include $(all-dl-routines), not just
 	$(dl-routines).
 	(rtld-routines): Likewise.  Use = rather than :=.
