This has been discussed, and there was a pretty strong consensus that we don't want `-ffreestanding`. Note that this is very different from supporting freestanding configurations. I also want to note that "most likely" is far from "will definitely never happen". Having that said, I don't really care whether it's in the commit message here or not. If you don't like it feel free to remove it.
