No -- we wouldn't want to call the m4 stuff in the external case, because what if it came to different answers vs. how the external one is configured? (e.g., if OMPI is built using icc and the external copy was built with gcc)
In the external case, OMPI should just use the external's hwloc.h and whatever decisions were already made there (sizes, types, etc.).
