Fixes this error when building on a single-CPU system:

=================================== FAILURES ===================================
_______________________ TestCoherenceModel.testProcesses _______________________

self = <gensim.test.test_coherencemodel.TestCoherenceModel testMethod=testProcesses>

    def testProcesses(self):
        get_model = partial(CoherenceModel,
            topics=self.topics1, corpus=self.corpus, dictionary=self.dictionary, coherence='u_mass'
        )

        model, used_cpus = get_model(), mp.cpu_count() - 1
>       self.assertEqual(model.processes, used_cpus)
E       AssertionError: 1 != 0
