Mesa (7.8): Change libX11 variables to not conflict with AC_PATH_XTRA

Module: Mesa
Branch: 7.8
Commit: 4e7a4bed372a6da4dde8926f3bc30c56e3fbe07b

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.
