From 7c3e8b642bad6669e0023d3d6dedd87b2527a2c8 Mon Sep 17 00:00:00 2001 From: Martin KaFai Lau Date: Thu, 19 Jul 2018 22:34:10 -0700 Subject: bpf: Use option "help" in the llvm-objcopy test I noticed the "--version" option of the llvm-objcopy command has recently disappeared from the master llvm branch. It is currently used as a BTF support test in tools/testing/selftests/bpf/Makefile. This patch replaces it with "--help" which should be less error prone in the future.
