3.19.8-ckt4 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Brenden Blanco <bbla...@plumgrid.com>
commit b88c06e36dcb9b4ae285f7821f62d68dc34b25d3 upstream.
in-source build of 'make samples/bpf/' was incorrectly
using default compiler instead of invoking clang/llvm.
out-of-source build was ok.
Fixes: a80857822b0c ("samples: bpf: trivial eBPF program in C")
