When `-Cstrip` was changed to use the bundled rust-objcopy instead of /usr/bin/strip on OSX, strip-like arguments were preserved. But strip and objcopy are, while being the same binary, different, they have different defaults depending on which binary they are. Notably, strip strips everything by default, and objcopy doesn't strip anything by default. Additionally, `-S` actually means `--strip-all`, so debuginfo stripped everything and symbols didn't strip anything. We now correctly pass `--strip-debug` and `--strip-all`.
