On some systems, libnuma can be present but it's so ancient that it misses some symbols that virNumaGetDistances() needs. To be more precise: numa_bitmask_isbitset() and numa_nodes_ptr are the symbols in question. Fortunately, they were both introduced in the same release so it's sufficient for us to check for only one of them. And the winner is numa_bitmask_isbitset().
