so, for practical purposes today, the extra ioctls in the s390 headers are not 
necessary and may safely be punted.  i'm trying to unify all the duplicated 
ioctlent content and this was the only hold out.

if, down the line, we want to fix strace itself, we can do that.  then we'd 
add the size/direction info to all linux ports.
