you'll find luajit builds OK with gcc6 on 10.4 Intel

and there is an option to do this in texlive-bin:

--with-system-luajit

that leads to an error later on when something tries to for a rebuild the internal luajit for some reason, but that is easy to patch out too...

but -- drumroll -- it still errors out after that :>
