Build failure on macOS Sonoma 14.0 beta

[Marc Culler]

This appears to be a completely independent bug in Apple's new linker.
(You are linking with libgmp, but presumably that library was built with a
different linker.  And the "error" is different.) Once I knew what to look
for I found lots of issues with the new linker reported on the Apple
development site.  Perhaps we can assume that the new linker is still
unstable and eventually will be working.  In the meantime we can still use
the old linker.  I guess that we can just carry on and hope for the best.

Thanks, everyone, for your help with this.
