This not work when you testing some combination e.g. Z*inx and zve*,
but anyway I guess those configurations are not matter for you guys :P
What you could do is install a suitable binfmt handler, then you don't 
need the wrappers at all.  That's how we're handling this stuff in 
Ventana.  It also means you don't need magic dejagnu baseboard files or 
anything like that.  In fact from dejagnu's standpoint it looks native.
