libero: add dummy Makefile

fusesoc relies on the Makefile timestamp to know if it should rerun the setup stage. Add a dummy file so that one can launch build and run stages without having to destroy and regenerate a project. This should be removed when updating libero to the flow api. Signed-off-by: Liam Beguin <[email protected]>
