I am Ok with this as it is specific to powerpc64le and will not impact
the other PPC platforms.

But I would prefer a compile test for __float128 and the require 'q'
suffix builtins over s GCC version test. This would allow for clang/llvm
compiles (once they complete their float128 support).

I approve with the change noted above.
