I've covered this issue in RFC for reproducibility. Bitbake is 
statically configured tool, so it prepares pipeline *before* start of 
execution. Parsing 'debian/control' assumes that you have already done 
do_fetch() and do_unpack() for specific recipe.

But in theory I see only the following for now:

  - Double bitbake re-run: first step fetch/unpack, second stage parse 
and prepare pipeline.
  - Modify bitbake.

I consider this as hack and not as proposal.

I'll continue this investigation.
