  Non-PIC shared libraries are unsupported on s390 64-bit (s390x).  The
compiler may perform optimizations that result in symbols:wq not being
overridable or reachable.  The latter may cause dynamic relocations to
overflow, resulting in run-time errors, such as segmentation faults.

Changes in v2:
- Report untested non-PIC load offset visibility linker tests.
- Skip non-PIC shared library visibility linker tests on s390 64-bit
  (s390x). (Alan)

Thanks and regards,
Jens

Thanks!  Committed only the s390 patch [2/2] to mainline, given that I
did not receive any feedback on the common ld testsuite patch [1/2].

Regards,
Jens
