On powerpc64le, support for float128 will be enabled, which requires gcc
versions greater than or equal to 6.2.
Tested for powerpc64 and powerpc64le.

* sysdeps/powerpc/powerpc64le/configure.ac: New file with test for
the required minimum gcc version.
* sysdeps/powerpc/powerpc64le/configure: New, auto-generated file.
