[Beignet] Can Beignet be used with OpenCLIPP?

[Zhigang Gong]

Forgot to mention the instructions:

untar the file firstly, then invoke the following commands.

# cd OpenCLIPP-master/
# make
# cd Test-OpenCLIPP/
# make
# LD_LIBRARY_PATH=`pwd`/.. ./Test-OpenCLIPP
# cd ../Bench
# make
# LD_LIBRARY_PATH=`pwd`/.. ./Bench
