> My original patch assumes that `-no_fixup_chains` would be silently ignored
by intermediate linker versions older than Xcode 13.  I have not yet tested
this assumption on any such Macs.

This is not a good assumption, I'm afraid. I personally tested this a while
back and found that older versions of ld64 will error when passed the
`-no_fixup_chains` flag.

See https://github.com/pybind/pybind11/pull/4301#issuecomment-1446551317.
(Unfortunately, the actions logs are no longer available from those tests.)
