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.

Daniel P. Berrangé <berrange(a)redhat.com&gt; writes: We do have reasonably good coverage with tests/tcg/cris but of course without a compiler we can't build them. Both nios2 and microblaze have build-toolchain scripts which can be used to re-create containers. However my preference is having pre-built toolchains hosted by others like we do for loongarch, hexagon, xtensa and tricore. Then the docker image can simply curl them into an image. -- Alex Bennée Virtualisation Tech Lead @ Linaro

Since 0b1a649047 (tests/docker: use direct RUNC call to build containers) we ended up with the potential for the remaining docker.py script calls to deviate from the direct RUNC calls. Fix this by dropping the use of ENGINE in the makefile and rely entirely on what we detect at configure time.
