Hi all,
After merging the tip tree, today's linux-next build (perf) failed like this:

I have reverted commits
a23b701ae9b3 objtool: Rework header include paths 1b4998c364bc objtool: Fix x86 orc generation on big endian cross compiles 317664a7fcc9 objtool: Fix reloc generation on big endian cross compiles 2a522b53c470 x86/insn: Support big endian cross-compiles 2486baae2cf6 objtool: Allow nested externs to enable BUILD_BUG()
for today.
This is a PowerPC LE native build of tools/perf.
