From 4e7a4bed372a6da4dde8926f3bc30c56e3fbe07b Mon Sep 17 00:00:00 2001
From: Dan Nicholson <dbn.lists@gmail.com>
Date: Mon, 15 Mar 2010 20:53:56 -0700
Subject: Change libX11 variables to not conflict with AC_PATH_XTRA

The variable X_LIBS from AC_PATH_XTRA contains only the -L searchdir
parameter and not the -lX11 to link to Xlib. Use X11 prefixed build vars
for linking with Xlib to avoid the conflict.

(cherry picked from commit e725ef171b5a4d5425461f237d9ccab223806913)
