Sure, but dpkg is part of build-essential too, and so AIUI it thus
needs to explain how it is supposed to build within the build-essential
bootstrap.

At the very best I'd make hurd-dev provide a libps-dev which dpkg would
depend on, but that'd be purely artificial since we don't actually ever
build a separate libps-dev package, the stage3 hurd-dev package already
provides everything that build-essential is supposed to provide.
