I may be not so experienced glibc developer, but isn't the
libc_hidden_proto macro used to bypass plt access to this function when
it is used internally in glibc?

For librt there is the same symbol (and stub function defined) for
backward compatibility.

Or am I missing something important? Thanks in advance for the
explanation.
