rs6000: Clarify overloaded builtin diagnostic

When a built-in function required by an overloaded function name is not
currently enabled, the diagnostic message is not as clear as it should be.
Saying that one built-in "requires" another is somewhat misleading.  It	is
better to explicitly state that the overloaded builtin is implemented by the
missing builtin.
