I ended up adding a new command line option to disable it for PPC, but it should be doable with the existing option of -enable-shrink-wrap=false if we don't want to add a new option. I think you can build this check into the checks for the ABI on a per-function bases and achieve the desired behaviour. 
Or, I misunderstand the question.
