[PATCH 2/3] PowerPC: PR target/70117, Force long double to be IBM 128-bit.
This patch fixes the pr70117 test to use IBM 128-bit long double.
I have run tests on a little endian power9 system with 3 compilers:
* One compiler using the default IBM 128-bit format;
* One compiler using the IEEE 128-bit format; (and)
* One compiler using 64-bit long doubles.
I have also tested compilers on a big endian power8 system with a compiler
defaulting to power8 code generation and another with the default cpu set.
Can I check this patch into the master branch?
