powerpc64le: Check for compiler features for float128
On powerpc64le, support for float128 will be enabled, which requires some compiler features to be present. This patch adds a configure test to check for such features, which are provided for powerpc64le since GCC 6.2. Tested for powerpc64 and powerpc64le. * INSTALL: Regenerate. * manual/install.texi (Recommended Tools for Compilation): Mention the powerpc64le-specific requirement in the manual. * sysdeps/powerpc/powerpc64le/configure.ac: New file with checks for the compiler features required for building float128. * sysdeps/powerpc/powerpc64le/configure: New, auto-generated file.
