[Mesa-dev] [PATCH] egl: fix OpenGL 3.1 context creation

[Timothy Arceri]

>From the EGL_KHR_create_context spec:

   "* If OpenGL 3.1 is requested, the context returned may implement
       any of the following versions:

         * Version 3.1. The GL_ARB_compatibility extension may or may
           not be implemented, as determined by the implementation.
         * The core profile of version 3.2 or greater."

Fixes CTS tests:
