[computer-go] Binary release of MoGo

[Hideki Kato]

Hi Sylvain,

Some computer-go friends in Japan have reported that even current 
binary of MoGo doesn't work on Athlon XP or Celeron.  Both (and 
Pentium III) have no SSE2 instructions while Pentium 4 has.

Could you please try -march=athlon-xp, pentium3 or generic?

Hideki
