At the moment I'm benchmarking both cores, Mercury and Cobalt.
Building Xenomai for Mercury core usage doesn't build xeno-test, among other
things.
If I understand correctly documentation at chapter Testing the real-time 
system
(both cores), it should get built for Mercury, shouldn't it?

Thanks,

Simone
