* PR158
	* libc/rcmd.c, libc/rcmd.c: Enable the rcmd() library call by
	commenting out the parts that deal with signals.  This enables
	RTEMS to 'rsh' command to a server connecting fd to remote stdio.
	The 'server-side' parts of this file which deal with authentication
	are disabled since they are not needed.
