Fair enough. I s'ppose we could put it in ompi/mca/common/hwloc and just let whoever link against it who wants to (e.g., individual components). Heck, we could just as well put hwloc down in opal -- e.g., opal/mca/common. Or something like that; maybe keep it up in opal/hwloc, but don't slurp it into libopen-pal -- just let things link against libhwloc_embedded if they want to.

Then even ORTE things could use hwloc, if desirable. So could paffinity/hwloc.

Hmm. There's probably both pros and cons to this approach. Need to think about that a bit...
