Bug#861133: tf: please make the build reproducible

[Chris Lamb]

Source: tf
Version: 1:4.0s1-19
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: uname

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that tf could not be built reproducibly as it embeds the output
of uname.

Patch attached.
