Bug#1148973: lemonade: please make the build reproducible

Source: lemonade
Version: 2026.39.1-1
Severity: wishlist

Hi,

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

This is because the package embeds a version number within one or more
of its binaries, but that fails (ie. if we are not being built from a
Git tree), then it will fallback to the current date.

A patch is attached that uses lemonade's own mechanism for overriding
the version number in the binary. This has the nice effect of including
the full Debian version number, including the -1 / -2 revision suffix.
