[Beignet] a question about gen-backend

[Rashid Kaleem]

I had the same problem when i was building the gen-backend. Make sure you
are using clang 3.3 when you compile. In my case, even though i had the
path to LLVM 3.3 setup, an older version of clang was also in my path, and
cmake was associating that as the C/C++ compiler.
