 [https://tex.stackexchange.com/a/378643 This StackExchange post] that
 Matthew pointed me to gives a clue as to as why this happens.

 I am going to comment out the `need`s that make us produce these files in
 Hadrian when we ask for the docs, for now, leaving a comment pointing to
 this ticket. Then as we figure out solutions to these issues (especially
 2), since that's GHC's CI system), we can put those PDFs back in and mark
 this ticket as solved.
