qemu-iotests doesn't run any guest code and I think almost all tests
only use the qtest or none machines. We can make sure that the remaining
one or two tests that do need TCG/KVM for some reason are not in 'quick'
group, so that './check -T -qcow2 -g quick' does the right thing (which
is also what 'make check-block' does internally).

Which are the cases that fail for you with '--disable-tcg'?
