[Buildroot] [PATCH 2/6] package/mesa3d: enable OpenCL support

[Valentin Korenblit <valentinkorenblit@gmail.com>]

Hi Thomas,

> From: Valentin Korenblit <valentinkorenblit@gmail.com>

> This patch provides Clover, the OpenCL 1.1 API implementation by Mesa
> for AMD GPUs. It generates libOpenCL.so.
>
> Add --disable-opencl-icd because in Mesa 18 it defaults to on.  When
> disabled, the shared library is named libOpenCL instead of
> libMesaOpenCL and CL headers are installed.
>
> Given that clc headers are being installed to a non-standard location,
> it is necessary to specify this path in configure.ac. Otherwise,
> pkg-config will output the absolute path to these headers located in
> STAGING_DIR, which will cause a runtime error when calling
> clBuildProgram.

Maybe it is clearer to write "OpenCL library headers", so we don't get confused
with Khronos OpenCL-Headers.
