The solution in Multiple PDF generation with one tex file worked with TeXLive 2015 and is now broken in TeXLive 2016, at least on OS X El Capitan.

Minimal Example:

\documentclass{article}
\ifx\conditionmacro\undefined
\immediate\write18{%
  lualatex --synctex=1 -interaction=nonstopmode -shell-escape --jobname="\jobname"
  "\gdef\string\conditionmacro{1}\string\input\space\jobname"
}%
\expandafter\stop
\fi
\begin{document}
asdf
\end{document}

Result with TeXLive 2015:

Any hints how one can get it running in TeXLive 2016?

\write18 no longer means execute system commands in luatex.

add 

\usepackage{shellesc}

to re-enable it.

That package will also allow the clearer syntax 

\ShellEscape{...}

instead of

\write18{...}

or since you are writing code specifically for luatex you could avoid using shellesc and use

\directlua{os.execute("\luaescapestring{...}")}

which would work in old or new luatex.
