The call to `ruby` is only needed to decide which ruby versions to run
the tests against. Since a crossbuild implies nocheck, no tests are ever
executed and the build just succeeds.

I just pushed a commit that marks everything but debhelper as
<!nocheck>, which makes crossbuilding work correctly (tested with the
newer sbuild only).
