Subject: [PATCH] Fixed compilation with current mesa versions.

As you can see in
https://cgit.freedesktop.org/mesa/mesa/tree/include/GL/glext.h
now the file uses __gl_glext_h_ instead of __glext_h_
It's precisely caused by commit f7d42ee7d319256608ad60778f6787c140badada

Backoprt notes: 

* The original patch adjusts auto/src/glew_head.h only
* include/GL/glew.h is not part of git repo and gets created on tarball
  creation

=> patch include/GL/glew.h either to cause the desired fix
