[Mesa-dev] [PATCH] Don't fail if libX11 isn't installed

[Daniel Stone]

configure.ac would previously refuse to complete if libX11 wasn't
installed, even if we'd disabled GLX and weren't building an X11 EGL
platform.  Make the check simply set the no_x variable that's used (but
never set) immediately below for what looks like this very case.
