powerpc64le: Enable float128
Add ulps for the float128 type, bits/floatn.h, and float128-abi.h.
Likewise, sqrt is not implemented in libgcc. The sfp-machine.h
header is taken from libgcc, and used to build a P7/P8 soft-fp
sqrtf128.
TODO: ldouble seems to have gotten worse. Did I break something?

powerpc64le: Require gcc >= 6.2 for powerpc64le
On powerpc64le, support for __float128 will start to be built by default,
which requires gcc versions greater than or equal to 6.2.
Tested for ppc64 (still works with older compilers) and ppc64le.

powerpc64le: Create divergent sysdep directory for ppc64le.
float128 requires the seemingly trivial addition of the
ieee754/float128 sysdep. This requires creating a bunch
of submachine and cpu directories and Implies files which
just point towards their powerpc64 equivalent.
Tested on P7, P8, and generic ppc64le targets with and
without multiarch.

float128: Enable use of IEEE wrapper templates
The templates for the IEEE functions wrappers implement wrappers that
do not rely on _LIB_VERSION / matherr / __kernel_standard
functionality to set errno and fix the return value of the functions.
The wrappers are ready to be used by all floating-point types, however
they will first be used by float128, since the old wrappers for float,
double, and long double need to be first deprecated and versioned.
This commits defines __USE_WRAPPER_TEMPLATE to 1 for float128 files,
so that the new wrapper templates are used for this type.

This leverages the _Generic feature of C11 as __USE_FLOAT128

Add support for testing __STDC_WANT_IEC_60559_TYPES_EXT__
This is defined by TS 18661-3 for supporting the _FloatN

This will also implicitly enforce a minimum GCC 4.9. Given
the standard is a C11 derivative, it would seem reasonable
to assume a C11 compiler with _Generic support. This allows
for much simpler type classification macros which in theory
should be supported on any C11 compiler.
