The functionality is more useful in a bare-metal environment, where it is common to have many variants of the same library. 

I discussed this with Peter Smith, and he agrees that the feature provides the most value in a bare-metal context. However, the principle of ordering libraries to preferentially select specific implementations is broadly applicable and is not unique to bare-metal systems. Therefore, I have removed the restrictions that previously limited this functionality on bare-metal targets.
