+    [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.
