I've found that the root cause is openvswitch selecting libunwind, and due to some mechanism I don't understand openvswitch isn't built anymore for 4.14 on buildbots already (though only for the most recent 4.14.x kernel version). Since everything else is working, I decided to push 5.4 support now and will be curious whether buildbots run through or not.
