Subject: [PATCH] PowerPC Fix ibm128 defaults for pr70117.c test.
This patch was previously posted as a combined patch with 2 other testsuite
patches. I moved it to a separate patch.
This patch fixes up a failure that I saw when I built a compiler with the long
double default set to IEEE 128-bit instead of IBM 128-bit. Now compilers with
either 128-bit long double default pass this test. Can I check this into the
master branch?

IEEE 128-bit.
