top: added a new #define to test absence of numa nodes

Catch-up with newlib, original commit message follows:
------------------------------------------------------

This new #define will produce top results identical to
the results achieved for './configure --disable-numa'.

However it keeps the change entirely local to our top.

[ it has been introduced to test the following patch ]
