[Beignet] Build failure with SVN LLVM (Fwd: AUR Comment for beignet-git)

[Zhigang Gong]

Just pushed a patch to master branch to enable clang build.

You can try to clean up the build tree, and configure it as below:

cmake -DCOMPILER=CLANG ../beignet

Then build. It works fine with my stock Clang/LLVM 3.5.0.
