This is a gigantic patch for an almost trivial issue. The current problem
is purely related to the fact that in a single location (nidmap.c) the
orte_process_name_t (which is a structure of 2 integers) is supposed to be
aligned based on the uint64_t requirements. Bad assumption!
Looking at the code one might notice that the orte_process_name_t is stored
using a particular DSS type OPAL_ID_T. This is a shortcut that doesn't hold
on the SPARC architecture because the two types (int32_t and int64_t) have
different alignments. However, ORTE define a type for orte_process_name_t.
Thus, I think that if instead of saving the orte_process_name_t as an
OPAL_ID_T, we save it as an ORTE_NAME the issue will go away.
