[Buildroot] [PATCH v2 1/1] package/mesa3d: Remove libGL headers/pkgconfig when OpenGL is disabled

[Yann E. MORIN <yann.morin.1998@free.fr>]

Bernd, All,

On 2015-06-07 23:11 +0200, Bernd Kuhls spake thusly:
> mesa3d defaults to --enable-opengl due to its weird configure.ac:

> 
> This leads to include/GL/*.h and lib/pkgconfig/gl.pc being installed to
> STAGING_DIR. These files are enough for other packages to wrongly assume
> that libGL.so is present, like vlc.

> Fixes
