There are two things at stake here: making Emacs builds reproducible,
and making Emacs produce deterministic output.

If autoload generation is non-deterministic, then every elisp package
ends up being non-deterministic.  So fixing it is a net win, and that’s
the reason why we started with this one.

The other issues affect only Emacs itself.  Timestamps and the likes are
easily addressed I guess.  Unexec is likely another story, though.
