It should not try to make any such target.
gnuplot-tikz.lua is itself the program, and does not need to be further compiled into 
an executable.

That looks more correct.  There should not be a target gnuplot-tikz.lua$(EXEEXT)

Lua is a language.   The file gnuplot-tikz.lua is executed by the lua interpreter
in the same way that  foo.sh is interpreted by the bash or sh or ksh interpreter,
or foo.py is interpreted by python or foo.pl is interpreted by perl.
There is no need to process gnuplot-tikz.lua into some other form during "make".
