Why?

By the same argument you could make support for int or anything else
optional for freestanding implemnentations.
Stuff that cannot be implemented easily on certain hardware should
surely be optional (or even better, the standard should try to avoid
introducing features in a way that make them hard or inefficient to
implement on certain types of hardware).

But I haven't yet seen a good reason to keep stuff like memcpy() that
can easily be implemented on any hardware on which C can be implemented
at all, optional.
