[PATCH, rs6000] Fix AIX test case failures

[Carl Love]

GCC Maintainers:

The following patch addresses test failures on AIX.  

The patch has been tested on 

    powerpc64le-unknown-linux-gnu (Power 8 LE)  
    powerpc64-unknown-linux-gnu (Power 8 BE)
    AIX 7200-00-01-1543 (Power 8 BE)

With no regressions.

Please let me know if the patch looks OK for GCC mainline.
