In response to that suggestion referenced below, these
changes allow display of task/thread level NUMA nodes.

Currently, only the 'top' program offers any NUMA type
support and it is limited to the Summary Area display.
With this commit both the 'top' and 'ps' programs will
be able to display NUMA nodes associated with threads.

[ this patch has been adapted from the newlib branch ]
[ and implemented so as to preserve the existing ABI ]

Reference(s):
#58
