Bug#896529: osmo-iuh: please make the build reproducible

[Chris Lamb]

Source: osmo-iuh
Version: 0.2.0-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps environment

Hi,

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

This is because it ships a header file containing the current
time and the current user in comments.

Patch attached.
