Hi, thanks for getting back to me!

I think a ./configure option could be an alternative. I'll CC the rest
of the reproducible-builds ML in case they want to jump in and call me
out :)

And yes, I think this has come up for other projects too, hence the
proposal of the S_D_E environment variable (for both setting a build
date and to indicate that this build should be reproducible).

Thanks again!
-Santiago.
