Refs trac:2952: temporarily turn off hwloc PCI support because it causes a

problem on SuSE 10 (which might be related to Oracle's dual-bitness
builds, but we aren't completely sure yet).

So just turn it off for now, and bring this over to v1.5.  Find a
proper fix (that enables pci support properly) for trunk/v1.7 later.
