[Beignet] [PATCH] cmake: Fix linking with LLVM/Terminfo

[Zhigang Gong]

This issue is caused by a LLVM 3.4 bug. I just haven't found a
good method to check the current LLVM is 3.4 and the LLVM was
built with Terminfo, then we can add tinfo into the LLVM_SYSTEM_LIBS
manually.

Simply add the tinfo into gbe link libraries unconditional is
not good. What do you think?
