meson: macos: Avoid warnings on Sonoma Starting with the Sonoma toolchain macos' linker emits warnings when the same library is linked to twice. That's ill considered, as the same library can be used by multiple subsidiary libraries. Luckily there's a flag to suppress that warning.
On Ventura meson's default of -Wl,-undefined,dynamic_lookup caused warnings, which we suppressed with -Wl,-undefined,error. Unfortunately that causes a warning on Sonoma, which is absurd, as it's documented linker default. To avoid that warning, only add -Wl,-undefined,error if it does not trigger warnings. Luckily dynamic_lookup doesn't trigger a warning on Sonoma anymore.
