It is, indeed. But if ./project1 defines export_headers, export_lib and 
project1 lib target, then project2 better link to "project1".

This way:
1. If project1 is available you link directly to the library, not to the 
staged version.

2. If project1 is not available then Jamfile in $(STAGE_DIR) will define 
project1 target and you will link to it.

Still no need to link to result 'stage' target.
