samples/bpf: fix in-source build of samples with clang
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") Signed-off-by: Brenden Blanco <bblanco@plumgrid.com> Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.
