[Beignet] [ANNOUNCE] Beignet 0.8.0

[Zhigang Gong]

Are you using LLVM/Clang 3.4?
If so, please check the notes for LLVM/Clang 3.4 in the README.md.

The root reason is llvm-config-3.4 has a bug which forgets to add -ltinfo in
the --libs even if the llvm/clang is built with terminfo.
There are three solutions here:
The first one is just to follow the guide in the README.md to rebuilt
llvm/clang without terminfo.
The second solution is to add tinfo into the beignet's cmake script, add the
following code into the CMake/FindLLVM.cmake.
if (LLVM_VERSION_NODOT VERSION_EQUAL 34)
set(LLVM_SYSTEM_LIBS, -ltinfo)
endif

The last one is to change to use LLVM/Clang 3.3 rather than 3.4.
