The intent of the configure directive "--enable-gcc-warnings" that states, "turn on
many GCC warnings (for developers; best with GNU make)" is, I guess, to warn developers of

Sorry, it looks like I misunderstood your bug report.
--enable-gcc-warnings is intended for developers, that is, people who are
maintaining or modifying coreutils. It tends to generate so many false alarms
that it is not intended for builders (people who are compiling and installing
coreutils). This particular diagnostic appears to be a false alarm, as coreutils
should configure and build just find if sys/sysctl.h is missing. So I suggest
either ignoring the warning, or omitting --enable-gcc-warnings, or (and this is
hardest suggestion, and meant only if you want to become a developer) developing
a patch that pacifies your compiler.
