Ok. So it will be possible to unsed everywhere and the line number/position
of the unset statement will decide based on the sequencial parsing of the
configuration file.

I would not be happy about this. Until bug 246061 dpkg-cross uses the
default approach and suite most of Makefiles. Changing that would lead to a
extensive configuration process not required today. It should be the default
to set the common used variables to confront the default.

The advantage of using dpkg-buildpackage -a<arch> would be reduced to a
subset of creating the *.changes and *.dsc files. That is not really helpful
in my point of view.

Yes, I approve this and would like to see a change here. This would make the
mode feature of dpkg-buildpackage -M<mode> more flexible and useful.

For me, it would be possible to switch between different compiler suites.
