Comment # 26 on bug 923486 from Michel Normand

(In reply to Takashi Iwai from comment #25)

* on my opensuse_13_2_ppc64le guest do an osc build of findutils
  and used generated test-lock outside and inside chroot environment
  as detailed below.
* Conclusion:
  with glibc-2.19-16.2.2 pass with  old libraries.
  with glibc-2.21-6.25   failure with last tumbleweed libraries.
