Apparently it's also possible to have a local intersphinx mapping file
which could be committed to git [1]. That obviously needs to be manually
updated occasionally, which is a bit tedious.
IIUC intersphinx also means that if a cross-reference target is not
present in the documentation being built, it'll use the canonical URL in
the intersphinx_mapping. So your locally built documentation for a
sub-book might contain links to kernel.org. I'm not sure whether that's
better or worse than broken links.
