IHMO, it's always best to build on identical machines. In theory they should work, but I have had problems when building packages where 32-bit AMD and 32-bit Intel systems had some incompatibilties that resulted in illegal instruction traps. One package I know gave me this was gmp, GNU Arbitrary Precision Arithmetic Library, required by clamav. Pretty much everything we build, we do with the OpenPKG portable package management system where the basic philosophy is to make it easy to build on the target machines thus avoiding this type of problem.
