AIUI, this is straightforward case of updating tools to use new option names. I suppose there is a chance it triggers failures in e.g. older linkers that don't support the newer names, but I assume on Apple platforms there's less risk of that anyway.

Do you happen to know when the new name was first added to the linker?
