Seems we are not the only project having trouble with this:

https://github.com/mesonbuild/meson/issues/12450

I had not realized that Apple recently wrote themselves a whole
new linker, but apparently that's why all these deprecation
warnings are showing up.  It's not exactly clear whether
"deprecation" means they actually plan to remove the feature
later, or just that some bozo decided that explicitly specifying
the default behavior is bad style.
