Bug#877375: polygen: please make the build reproducible

[Chris Lamb <lamby@debian.org>]

Source: polygen
Version: 1.0.6.ds2-17
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that polygen could not be built reproducibly due to iterating
over the filesystem in a nondeterminstic order.

Patch attached.
