Ralph Castain 54db4c35eb Get the trunk to build again when --without-hwloc is specified. Move a couple of key type definitions and utilities out from under the HAVE_HWLOC test so they are always available as they don't really depend on hwloc's presence. Tell two compnents not to build if hwloc is disabled:
ompi/mca/sbgp/basesmsocket
orte/mca/rmaps/lama

Remove stale configure.params files from the sbgp framework as the OMPI build system no longer looks at those files.
