I think it's fine not to have a new version there.  On architectures with 
architecture-specific exp versions or IFUNCs the new version serves a 
purpose even as an alias for a wrapper (it means that if in future those 
architectures change to avoid the need for wrappers, any binaries built 
since the new version was released will automatically benefit without 
needing to be rebuilt), but I don't see any such purpose when the 
architecture postdated SVID error handling support.
