Hm, is that a common practice on macOS to run binaries compiled on
newer version of the system? For instance, on Linux with glibc (using
versioned symbols) that wouldn't work.

I don't know, both seem like ugly hacks to me. I'd rather add a more
general "--without-clock-gettime" option to the configure script, so
you can disable it if you have a good reason, but leave the detection
enabled by default.
