Thanks, work around from the bug report solves my issue with beignet and 
I can successfully use OpenCL on that host.

Second host where I was testing against pocl has some other issue:
# clinfo

   Platform Name                                   Portable Computing 
Language
   Platform Vendor                                 The pocl project
   Platform Version                                OpenCL 2.0 pocl 0.14,
