[Buildroot] [PATCH v5 7/7] package/amd-catalyst: Add support for OpenCL

[Romain Perier]

The AMD Catalyst Linux driver includes OpenCL libraries for GPGPU
computing. This commits adds support to install the binary blobs and ICD
profiles.

Changes in v5:
 - Don't install libraries in /usr/lib32 or /usr/lib64, these symlinks
   don't exist. We prefer install these libs into /usr/lib directly
 - Changed the corresponding code to install libs to these paths
 - Use absolute file name for 'clinfo'
