FreeBSD 2.2.5-STABLE i386

>Description:

/var/yp/Makefile goes through great lengths to use unique temporary
filenames, except for one:  /tmp/ypmake

Two invocations of make will stomp on /tmp/ypmake.  One will exit with a
file not found error, and the other will install a truncated
master.passwd.byname, and all the sudden mail starts to bounce as 75% of
the users disappear...

>How-To-Repeat:

Change your password on a yp client (which invokes rpc.yppassdd) at the
same time will an admin is doing a "make" to update the maps.


>Fix:
	
/var/yp/Makefile needs to postfix some unique info on /tmp/ypmake
