look in /proc/cpuinfo for flags, my guess is 533 (p2-based, might be p3) = 
mmx 650 (p3 based)= mmx, mmx2, sse (--disable-mmx --enable-mmx etc)

you can also use runtime cpu detection 

enable whichever option in the configure script

You need to have the same libraries, or equivelent versions on the machines. 
<- very important, otherwise it may compile but not work.
