Bug#720092: Please package ocl

[Nobuhiro Iwamatsu]

Hi,

I made sure that there is implementation of DFSG-free of OpenCL by Mesa 10.
Mesa 10 is not installed in to Debian, this is no problem.
And there are pocl as implementation DFSG-free using ocl-icd.
This is packaging by ocl-icd maintainer.
I will enable ocl library, and upload soon.

Thanks for your help and comment!

Best regards,
  Nobuhiro
