Bug#1148977: yuzu: please make the build reproducible

[Chris Lamb]

Source: yuzu
Version: 0-1734+ds-9
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

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

This is because it generates a version number via stat(1), but the output
of this command will vary on the local timezone. A patch is attached that
will always use UTC when generating this value.
