bpf needs 3.7.1 and higher version. Later clang (>= 3.7.1) has more features.
In the kernel tree it is documented here:
https://github.com/torvalds/linux/blob/master/samples/bpf/README.rst

But the kernel says:
clang >= version 3.4.0 + llvm >= version 3.7.1

What is your 'llc' version?
(run command: llc --version )
