Bug#779161: eo-spell: please make the build reproducible

[Chris Lamb]

Source: eo-spell
Version: 2.1.2000.02.25-49
Severity: wishlist
Tags: patch

Hi,

While working on the "reproducible builds" effort [1], we have noticed
that eo-spell could not be built reproducibly.

The attached patch removes timestamps from the build system. Once
applied, eo-spell can be built reproducibly in our reproducible
toolchain.
