There is no point. Packages must use dpkg-architecture,
dpkg-buildflags,... or the respective makefile sniplets in
/usr/share/dpkg/ in case debian/rules is called directly, they must not
rely of dpkg-architecture setting them.

Hopefully dpkg-buildpackage will stop setting those varibales at some
point so sources that wrongfully depend on the variables being set
actualy break.
