Use shorthand linker strip arguments in order to support MacOS

Per discussion from #72110 (comment) onward, the current `-Z strip` options aren't supported by the MacOS linker, but I think only because it doesn't support the longhand arguments `--strip-debug` and `--strip-all`.

This PR switches to using the shorthand arguments `-s` and `-S` instead, which (I believe) are supported by all GCC linkers.
