I have little to add on the underlying issue or non-issue but some
ideas on how to solve your problem

If your makefile depends on checkout, why not
  git ls-files | xargs touch
or if this done in an environment where there's not a fresh clone each

  git diff HEAD --name-only --diff-filter=AM | xargs touch
or something along those lines
