This sounds like an old problem 

https://tug.org/pipermail/luatex/2013-May/004208.html

The issue I opened at the time has been closed in 2015 as resolved
http://tracker.luatex.org/view.php?id=827

But when I test now Hans example there I get a "not found" for the
first case with "\openin0 makefile", so it looks as if some
regression has happened.
