It works for me.

I applied Vivien's v9 series and backed out the abilist changes using:

  git checkout origin/master '*.abilist'

Then I built glibc, and ran “make t=elf/check-abi-libc test”.  It failed
as expected:

FAIL: elf/check-abi-libc
original exit status 1

As far as I can see, this updates all libc.abilist files with the
expected changes (and shows that many are still missing from the v9
series).

Thanks,
