>Description:
As far as I understood the discussions and patches during the recent weeks, all JIT features of LuaTeX have been disabled. Unfortunately, the configure script of print/luatex still fails fatally on Sparc (and probably other exotic platforms) with

configure: error: Sorry, can not preprocess <lj_arch.h>

which means that all depending TeX packages can't be build.
>How-To-Repeat:

>Fix:
Make the dependency on print/tex-luatex optional in (at least)

print/tex-latex/Makefile
print/texlive/package.mk

The correct fix upstream is probably to skip the JIT check if all JIT features have been disabled.
