Bug#1118596: ne: please make the build reproducible

[Chris Lamb]

Source: ne
Version: 3.3.4-1
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
ne could not be built reproducibly.

This is because it embeds the current build date. A patch is attached
that will use SOURCE_DATE_EPOCH (if available).
