The change in c12 is ok if you'd like to do that.  The only problem with it is
that then we will not be able to discover when radr://19802258 is fixed.  When
people notice that that bug is fixed, we should revert the c12 patch. 
Essentially, we allow the test case to track any _other_ issue that prevents
things from just working (to catch any regressions), so that when ld64 is
fixed, the test case will remain working.
