From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Subject: tools/objtool/Makefile: don't assume sync-check.sh is executable
patch(1) loses the x bit. So if a user follows our patching instructions
in Documentation/admin-guide/README.rst, their kernel will not compile.
Fixes: 3bd51c5a371de ("objtool: Move kernel headers/code sync check to a script")
