rcmd.3: ATTRIBUTES: Note functions that are/aren't thread-safe 

After research, We think
* rresvport(),
* iruserok(),
* ruserok(),
* rresvport_af(),
* iruserok_af(),
* ruserok_af(),
are thread-safe. And
* rcmd(),
* rcmd_af(),
are not thread-safe. But, there are not
markings of them in glibc document.
