Bug#1050727: zlib: please make the build reproducible

[Chris Lamb]

Source: zlib
Version: 1:1.2.13.dfsg-3
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

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

This is because it embeds the absolute build path in the minizip and
miniunzip scripts.

A patch attached that uses sed to remove these, (although there might
be a cleaner way to inform autotools/libtool to not do this code
injection).
