In windows case I would like to disagree. this is a way to run test in 
emulated environment. Build system run in emulator a native executable 
(libtool wrapper executable) , then wrapper set environment and spawn 
real executable.
This is specific for this case and know emulator. I would like to inform 
you that shell-wrapper from pre-libtool  2(.2?)  era can not be used in 
this case.
May be I misunderstand you idea .
Please detail you case.
