Hi,

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

This is because the build system embeds timestamps in its man pages:

├── ./usr/share/man/man1/dub-add-local.1.gz
│ ├── dub-add-local.1
│ │ @@ -1,8 +1,8 @@
│ │ -.TH DUB-ADD-LOCAL 1 "2025-05-24" "The D Language Foundation" "The D Language Foundation"
│ │ +.TH DUB-ADD-LOCAL 1 "2024-04-21" "The D Language Foundation" "The D Language Foundation"

(etc.)

A patch is attached that simply exports dub's custom DIFFABLE
environment variable. This was seemingly introduced to make these
manpages, well, 'diffable' — that is to say, so that they generated in
a deterministic manner.
