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.

 * sysdeps/powerpc/fpu/libm-test-ulps: Regenerated.
 * sysdeps/powerpc/fpu/math_private.h:
 (__ieee754_sqrtf128): New inline override.

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.
