+Subject: [PATCH] build: Don't fail if libX11 isn't installed
+
+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.
