this only takes care about packages with a reduced package set built, or
packages with reduced functionality. There are same cases missing:
- extra build dependencies for cross builds, like for gcc-4.7:
- build dependencies for running the check target. Usually these
dependencies can be ignored when cross-building packages, or when
building a package natively with DEB_BUILD_OPTIONS=nocheck.
profile:check? There are not few packages which can be easier
cross-built when identifying and dropping these build dependencies.
So it does make sense to build with two profiles like stage1 & check.
