[meta-freescale] Vivante OpenCL Examples Source

[Sébastien Taylor]

User needs libCL to use OpenCL, to do anything useful you need to compile kernels (shader programs) using libCLC (CL Compiler).  Though technically a pre-compiled shader could be loaded without the need of libCLC I'm not sure if the Vivante libraries actually support this (to pull the objects back out from libCLC).  The fact that libCL silently fails compilation when libCLC is missing is what would lead me to consider both are required for OpenCL.

I understand that it makes sense to separate the CL and CLC libraries as one might want to use pre-compiled .cl files but the silently failing is an issue.  This is all of course all Vivante and uncontrollable by Yocto.  As far as Yocto is concerned libCL.so and libCLC.so should probably be considered interdependent by default.
