* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): If GLIBC
provides the hardware capability bits, define the macro
__BUILTIN_CPU_SUPPORTS__.
* config/rs6000/rs6000.c (cpu_expand_builtin): Generate a warning
if GLIBC does not provide the hardware capability bits. Add a
gcc_unreachable call if the built-in cpu function is neither
__builtin_cpu_is nor __builtin_cpu_supports.
* doc/extend.texi (PowerPC built-in functions): Document that
GLIBC 2.23 or newer is needed by __builtin_cpu_is and
__builtin_cpu_supports. Document the macros defined by GCC if the
newer GLIBC is available.
