Xcode 15 beta claims to also support macOS 13/Darwin 22, though I
haven't tried this.

Agreed: those incompatibilities are pretty messy. It seems Apple has
changed a considerable part of the cctools (or however they call it
those days) codebase. dsymutil is another case which now warns
warning: '.debug_macinfo' is not currently supported: file will be skipped
note: while processing const1.o
in quite a number of cases where the previous version didn't.

Right: there's an actual ld-classic binary (and manpage) which still
identifies itself as ld64.
