[OE-core] [RFC][PATCH] mesa-gl: add GL-only Mesa recipe

[Kamble, Nitin A]

With few more fixes, this is working for EMGD based meta-intel BSPs. 
Here are the commits which worked:

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=nitin/mesa-gl
http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-contrib/log/?h=nitin/mesa-gl

BTW the same functionality can also be implemented by customizing current mesa 
recipe based on a new machine feature which can be called as
"custom-gles" or "no-mesa-gles"

BTW in other context, this does not help for the rebuild issue RP was mentioning earlier.

Thanks,
Nitin
