[powerpc] fenv_libc.h: protect use of __builtin_cpu_supports
Using __builtin_cpu_supports() requires support in GCC and Glibc. My recent patch to fenv_libc.h added an unprotected use of __builtin_cpu_supports(). Compilation of Glibc itself will fail with a sufficiently new GCC and sufficiently old Glibc: ../sysdeps/powerpc/fpu/fegetexcept.c: In function ‘__fegetexcept’: ../sysdeps/powerpc/fpu/fenv_libc.h:52:20: error: builtin ‘__builtin_cpu_supports’ needs GLIBC (2.23 and newer) that exports hardware capability bits [-Werror] Reviewed-by: Florian Weimer <fweimer@redhat.com> Fixes 3db85a9814784a74536a1f0e7b7ddbfef7dc84bb.
