Dear Maintainer,

Thanks to the SOURCE_DATE_EPOCH [1] support in TL2016, pdf output of
makeinfo can be made reproducible, even when using @today in the texi
file (when SOURCE_DATE_EPOCH_TEX_PRIMITIVES is set to 1).

It would be great to extend the SOURCE_DATE_EPOCH support for info
output from makeinfo. See a proposed solution in the attached patch.

Regards,
Alexis Bienvenüe.

Description: Reproducible info output
 Honour the SOURCE_DATE_EPOCH environment variable to get a reproducible
 @today value for info output when it is set.
