Ralph won't be on the call today, but asked if we could discuss internal HWLOC 2.0.0a PR 3951
- Cisco did some sanity checking, They all seem to be working properly.
- Don't know if external component can handle the new hwloc 2.0.0a
  - Some minor breaks from hwloc 1.x to 2.0. Don't know if this PR handles the external.
- If this PR doesn't update the external component, then we'd file a blocker issue to allow external to support hwloc 2.0.0.
dlopen RTLD_LOCAL for python bindings
- Other's please test platforms and update platforms.

Howard is trying to figure out something with popen, which is why there's a lot of failures in that area.
