getconf(1) itself is POSIX, while `_NPROCESSORS_ONLN' is not. However, FreeBSD (tested 11.4 and 12.1) and glibc (tested CentOS 7.x and Debian 10.x) both support `getconf _NPROCESSORS_ONLN'. GNU coreutils (and thus `nproc' or `gnproc') are not installed by default on the *BSDs, so we'll try the option most likely to exist on both glibc and *BSDs out-of-the-box.
