bug#47592: [WIP Emacs] Emacs packages, that fail to build on master

[Leo Prikler <leo.prikler@student.tugraz.at>]

I'm currently in the process of verifying, that all Emacs packages
build in the wip-emacs branch.  To that end, I'm running a manifest
generated from all emacs-xyz exports, which will fail for some package,
that I've broken, then rinse and repeat.
However, there are some build failures, that exist not only in wip-
emacs.

In order not to generate too many bug numbers, I'm filing this as some
sort of meta bug.  Fixes could likely be pushed directly to master, but
if it's fine for everyone to wait a little, I'd send them through wip-
emacs first.

Regards, 
Leo
