While I think your suggestion is the proper solution I do not think that
it is worth the effort.  I would rather do the following:

  1. Exclude those test that are failing (it is only a small number)
     for the architectures where the test fails).  Please do not hesitate
     to ask here if you are lacking ideas how to do this.  May be the
     python-cogent package can serve as an exemple.  Its probably
     sufficient to do something like this:

	ifeq ($(BUILDARCH),...)
          mkdir tempdir
          mv test/... tempdir
          dh_auto_test --sourcedirectory=test
          dh clean --sourcedirectory=test
	ifeq ($(BUILDARCH),...)
          move back files to restore original source state
          rmdir tempdir

  2. Since you have saved time to work out proper tests on rarely
     used architectures you have time to package

While the later is half joking this could be quite useful.  You would
have need the tool for your original plan - may be for other things as
well and you could learn packaging.

Kind regards
