Thanks for posting the updated series.

I tested this with  build-many-glibcs.py, and ran into an ICE on tile*. 
Filed as:

   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78862

The good news is that ABI and PLT checking passes everywhere.  Yay!

The explicit_bzero test case (string/tst-xbzero-opt.c) now fails.  This 
is probably  test case bug, for which I will post a patch shortly.

I'll go through the updates series again, probably tomorrow.

Thanks,
Florian
