Latest master broken on Cocoa/NS

Hi Dmitry,

This commit seems to be the culprit:

  commit 20038f8ab75dd1551412a43cd58520c483c22921
  Author: Dmitry Antipov <dmantipov@yandex.ru>
  Date:   Tue Jul 12 09:16:26 2016 +0300

You add a frame argument to Fx_hide_tip and a corresponding call, but
apparently forgot to take care of nsfns.m, which also declares it for
use in the NS build:

   menu.c:1407:20: error: too many arguments to function call, expected 0, have 1
         Fx_hide_tip (frame);
         ~~~~~~~~~~~  ^~~~~
   ./globals.h:4300:1: note: 'Fx_hide_tip' declared here
   EXFUN (Fx_hide_tip, 0);
   ^
   ./../lwlib/../src/lisp.h:691:3: note: expanded from macro 'EXFUN'
     extern Lisp_Object fnname DEFUN_ARGS_ ## maxargs
     ^
   1 error generated.

The patch after my sig apparently fixes it...
