So long as you don't specify a particular CPU type in your compilation flags -- ie. leave the flags at their default settings -- then it should be absolutely fine to build on any amd64-compatible machine to deploy on practically any other amd64-compatible machine. Compilers on FreeBSD are configured to support a generic CPU which all more recent designs than the Intel 486 or 586 should be backwardly compatible with. After all, the cerntral FreeBSD package build servers are pretty highly specified rack-mount servers, but the packages built on them are expected to work on much older and less capable hardware.
