hoping to compile Crafty numa aware ...

so far here is the best crafty 19.19 bench mark I have obtained under 19.19 ...

crafty64 19.19
dual opteron 244
oc 2.1 Ghz
default hash

Total nodes: 117483081
Raw nodes per second: 4195824
Total elapsed time: 28
SMP time-to-ply measurement: 22.857143

big hash saves ~14% in time, although 1.5% slower nps, it reduces the nodes
search to reach the given depths by 17%, saving 4 seconds

Crafty version 19.19
hash table memory =       384M bytes.
pawn hash table memory =   96M bytes.
White(1): bench
Running benchmark. . .
