Upstream relevant discussion: https://www.mail-archive.com/cfe-commits@cs.uiuc.edu/msg122512.html (no fix yet) In the meantime, reverting this commit or disabling USE=doc should workaround the problem
Until someone (upstream or a doc expert) fixes the problem, I added a patch to remove the problematic references. So -9999 doc should build again
Ebuilds >=3.7.0-r1 now use -DSPHINX_WARNINGS_AS_ERRORS=OFF, a cleaner fix
