We had a need for something similar to this. I found that marking the
feature like the following adds an output directory named with the
feature domain : Domain1 Domain2 : implicit propagated link-incompatible ;
feature cryptoengine : Crypto1 Crypto2 : implicit propagated link-incompatible ;
This seems to work OK with 'bjam' 3.1.16.
