In this situation, I guess there are two possibilities:

1) You run "dpkg-source -b" yourself, then run sbuild with the
   resulting .dsc.  This won't require any changes to sbuild directly.

2) We add an option to sbuild to permit cleaning of the tree to be
   skipped.  I guess we can add -nc like for dpkg-buildpackage.

It depends on whether (1) is too much of an inconvenience.  But it's
certainly possible to do (2).
