I never understood what this option was good for and now it gives a warning about being unused during compilation (even though it was set only during linking).
Basically libraries referenced indirectly will be setup as a requirement of the target and this option strips that. Doesn’t really matter, but enabling it rather than deleting the line (which was previously commented).
We now explicitly disable it for targets that hasn’t yet been upgraded to ARC. This way, it’s easier to get an overview of which targets hasn’t yet been upgraded and ensures new targets has ARC enabled.
