Bug#1109484: rust-microformats: please make the build reproducible

[Chris Lamb]

Source: rust-microformats
Version: 0.15.0-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: filesystem

Hi,

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

This was because it was generating a bunch of tests that were ordered
by the underling filesystem order, which is of course non-deterministic.

A patch is attached that sorts the filenames first.
