Historically, Sphinx was required when building "standalone" builds,
else they would have no man pages.
This means that commit 0709e4be8b (Use standalone code paths by
default, 2025-10-26) broke man pages for users who build from a
tarball where non-standalone builds would use prebuilt docs.
Add a hack to use prebuilt docs again.
In future, we'll remove prebuilt docs, see #12052.
