I don't think this is the right approach here. `_LIBCPP_USING_IF_EXISTS` is there to make `std::strtok` available exactly when `::strtok` is available, which seems like a _much_ more useful way of handling this than arbitrarily disabling it because `-ffreestanding` was set. Generally, I don't think we should check for `-ffreestanding` directly in the headers at any point.
