[Reproducible-builds] lua-ldoc --date/SOURCE_DATE_EPOCH

[Alexis Bienvenüe]

Hi.

lua-ldoc's maintainer added a --date option that helps reproducible
building. It is used by lua-penlight.
However, awesome and lua-posix don't use it already.

What should you recommend?
1) patch awesome and lua-posix to use --date
2) patch lua-ldoc to add SOURCE_DATE_EPOCH, on top of --date. This would
be more reliable, but maybe lua-ldoc will get a little messy/muddled?

Thanks for your advice,
Alexis Bienvenüe.
