The *_arg functions are intended to be generally useful -- especially in
conjunction with dwarfless probing, where there's no other practical way to
refer to args.  The problem is that -- as you've noted -- they haven't been
ported to s390 or ia64 (or arm).  So it would probably be best to purge the
syscall tapset of calls to these functions.
