For ELF systems there does not seem to be much point in running
    	/etc/rc.d/ldconfig to generate the 'a.out runtime link editor
    	directory cache'. At the very least there should be an rcvar
    	for it, and I would suggest defaulting it to 'off'.
   
    	The only port that is still a.out is pc532, which is stuck at
    	1.5.3 anyway.
   
    	Would anyone have any objections to such a change?


hmmm.  perhaps the default should depend on whether something is
in /emul/aout/usr/lib or not?  ie, this feature *is* useful for
people running a.out binaries and turning this off by default may
cause weirdness for them.

is there an actual problem here?
