We move a couple of targets out of the avocado runs because there are
no tests to run. Tricore already has some coverage.  The cris target
only really has check-tcg tests but its getting harder to find
anything that packages the compiler.

To reduce the noise of CANCEL messages we also set AVOCADO_TAGS
appropriately so we filter down the number of tests we attempt.
