[RFA] darwin-nat.c AR Index fixes: remove strerror uses

["Pierre Muller" <muller@ics.u-strasbg.fr>]

  This patch could be consider 
under the obvious rule,
but as it is a native file, I still wanted to
get an approval from someone 'who knows'...

  But I didn't find anyone in MAINTAINERS
for the darwin* files...

  Is this OK  to check in?

	ARI fix.
	* darwin-nat.c (darwin_ptrace): Use safe_strerror.
	(darwin_stop_inferior, darwin_attach, darwin_detach): Ditto.
