X-Git-Tag: v4.19~1852^2

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")
