hurd dl-sysdep.c fix

[Roland McGrath <roland@frob.com>]

Here is a trivial patch to today's CVS repository that made libc build ok
for the hurd for me (not that it actually runs, I haven't tested it).  This
probably duplicates some of Mark Kettenis's changes, but this is relative
to the CVS state as of right now.


1998-07-19  Roland McGrath  <roland@baalperazim.frob.com>

	* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): #if 0 out the
	magic memobj port arg parsing stuff.  Fix it someday when we are ready
	to really use it.
	(_dl_sysdep_output): New function, modified from _dl_sysdep_error.
	(_dl_sysdep_error, _dl_sysdep_message, _dl_sysdep_fatal): Removed.
