The attached patch makes lintian stop emitting the latter tag for 
python-central and python-suppport. (Probably similar thing should be 
done for for dh-ocaml, but it's not _that_ easy.)

However, there are some gotchas:
- missing-build-dependency has higher severity than 
...-for-dh_-command.
- missing-build-dependency is on ftp-masters' auto-reject list, 
automatically ...-for-dh_-command is not.

Couldn't we merge these two tags into one? If there's a reason to keep 
them separate, at least severity should be unified and ftp-masters 
should be asked to add ...-for-dh_-command to their list.
