On OS X Big Sur (intel), as of the most recent Xcode and homebrew, I am
currently unable to build Sage with either homebrew's Python or with
`./configure --with-system-python3=no`.
- With homebrew's Python, actually Sage builds but the documentation does
not (similar problems on both Big Sur and Catalina), ending with

Unhandled SIGILL: An illegal instruction occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.

- With `./configure --with-system-python3=no`, Python fails to build (on
Big Sur only; it succeeds on Catalina), saying
ModuleNotFoundError: No module named 'readline'
and
ModuleNotFoundError: No module named 'zlib'
Any suggestions?
