I ran "brew upgrade" recently on two different Macs, one Intel and one
Apple Silicon, and now the Sage documentation fails to build:

(I saw this first with 10.0.beta6 but then went and tried with 10.0.beta5,
which had succeeded earlier. Now it fails.)
Perhaps this is due to an upgraded openblas? That's the most obvious among
the recently upgraded packages, at least to me: homebrew just upgraded
these:

"brew info openblas" says that it's version 0.3.22, whereas Sage comes with
0.3.21. Everything works after building with `./configure
--with-system-openblas=no`, but that flag triggers some other packages to
be built by Sage rather than come from the system, so I'm not 100% sure
it's the issue.
Has anyone else seen this?
