Since v2:
- Run check-qtest instead of check-unit in CI (Alex)

Almost 2 years later we got hundreds of cleanups patches
merged, so we can get this patch in. Building the 'any'
target has to be explictly requested in ./configure
target-list argument.

This binary will be use to rework QEMU startup code,
paving the way toward dynamic machines. It might also
allow experimenting with multiple TCG target frontends
and possibly prototyping concurrent HW/SW accelerations.

The corresponding CI jobs takes <3min!!!
