* hurd/hurdstartup.c (_hurd_startup): Use new

Browse Source 
exec_startup_get_info RPC from exec_startup.defs
	in place of old exec_startup from exec.defs.  Remove kludge to
	guess user entry and phdr locations, since the new RPC gives us
	that info.

	* sysdeps/generic/_strerror.c: Undo last change.
