Adding ifuncs makes sense for other reasons. But I still don't see why 
we should add the proposed tunable.

The proposed tunable wouldn't make GNU/Linux programs more reliable, or 
faster; on the contrary, it would make them a bit harder to develop and 
maintain.

As far as I can tell, the proposed tunable's main goal is to make 
GNU/Linux programs more portable to IBM AIX (and hypothetically to 
other, even-more-obscure systems). But no users have asked for this. And 
the goal is not worth the 
development/maintenance/documentation/administrative/etc. overhead of 
adding such a tunable.
