1.33: sphinx warnings `reference target not found`

[kloczek]

On building my packages I'm using sphinx-build command with -n switch which shows warmings about missing references. These are not critical issues. Here is the output with warnings:

```console + /usr/bin/sphinx-build -n -T -b man doc build/sphinx/man Running Sphinx v6.2.1 making output directory... done building [mo]: targets for 0 po files that are out of date writing output... building [man]: all manpages updating environment: [new config] 4 added, 0 changed, 0 removed reading sources...

I don't quite understand why sphinx does not find the references. Any idea?
