[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?
