* configure.ac:
	* clutter/cogl/gl/cogl-defines.h.in: The OS X backend has a funny
	OpenGL header location, so it basically did break every application
	including clutter/cogl.h because the GL header inclusion depended
	on symbols defined into Clutter's config.h. Now, we define the
	GL header into the configure template and use it to create the
	cogl-defines.h file cogl.h includes.
