When I want to build a package for the native architecture, I don't
need to be root. If there are missing build dependencies, then the
missing packages are listed, so that I can install them as root,
then I can retry the package build as a normal user. So, the only
things I do as root is to install packages. The build is entirely
done as a normal user.

Or perhaps I can try pbuilder-user-mode-linux.

The issue is that all this will require a major rewrite of my
scripts...
