[luatex] LuaTeX 1.09.2 does not build

[Henri Menke]

Dear list,

Running the build of LuaTeX 1.09.2 with the simple command

    ./build.sh --parallel --jit

results in an error:

    make: *** No rule to make target 'luatex53'.  Stop.
    strip: 'build/texk/web2c/luatex53': No such file

That is due to the fact that Lua 5.3 is now default and Lua 5.2 has been
removed, i.e. the option --enable-luatex53 is no longer available.  As a
temporary workaround one can use

   ./build.sh --lua52 --nolua53 --parallel --jit

Please fix the build.sh script.

Cheers, Henri
