To verify if you are using a GNU Coreutils su program you can use:

  su --version

A GNU program is supposed to tell you its version (see for example "ls
--version"), while the non-GNU su program on my systems does not recognize
this option:

$ su --version
su: unrecognized option '--version'
Usage: su [options] [LOGIN]
[...]
