This might be premature but while streamling the avocado tests I
realised the only tests we have are "check-tcg" ones. The aging
fedora-criss-cross image works well enough for developers but can't be
used in CI as we need supported build platforms to build QEMU.
Does this mean the writing is on the wall for this architecture?
It was deleted in Linux, and GCC dropped the cris-*linux target,
but GCC keeps other cris targets.
IOW, at very least, it has become a niche use case target.
We don't need Linux/GCC support as a pre-requisite for having a
target in QEMU, but it sure makes it increasingly challenging
to test.
