+==================== Work086, patch #1:
+
+Disable float128 tests on VxWorks.
+
+In PR target/104253, it was pointed out the that test case added as part
+of fixing the PR does not work on VxWorks because float128 is not
+supported on that system.  I have modified the three tests for float128 so
+that they are manually excluded on VxWorks systems.  In looking at the
+code, I also added checks in check_effective_target_ppc_ieee128_ok to
+disable the systems that will never support VSX instructions which are
+required for float128 support (eabi, eabispe, darwin).
