Hi,

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

This is because the build system embeds the output of calling "date":

│ │ │ ├── ./usr/lib/ispell/esperanto.aff
│ │ │ │ @@ -1,13 +1,13 @@
│ │ │ │  # -*- coding: latin-3 -*-

Patch attached that replaces this with a call to the Debian-specific
"dpkg-parsechangelog -SDate". However, you could make this distribution
agnostic by calling date(1) seeded by SOURCE_DATE_EPOCH if it exists…
or simply by removing this date entirely.
