[DRE-maint] Bug#849972: yard: please make the output reproducible

Source: yard
Version: 0.9.5-1
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that yardoc generates output that is not reproducible due to the
use of a fallback glob that relies on (non-deterministic)
filesystem ordering.

Patch attached.
