Segher, David:
I reworked the patch per the first option that David gave. The tests
divkc3-2.c, divkc3-3.c, mulkc3-2.c and mulkc3-3.c pass on Power 9 Linux
as they did before. The tests are unsupported on Power8 Linux as they
were before. Now, the tests are reported as unsupported on AIX rather
then failing on AIX.
Please let me know if you both approve the updated patch below. Thanks
for the input and help on this.
