Historical note: I once had support for multiple architectures built into FreeBSD's GNU tools with the host architecture set as the default. I was heading for being able to build Windows programs on FreeBSD as well. It is (or at least was) possible to do, but FreeBSD has has the approach of tools built for the host machine arch or cross-built tools built for the target architecture. With support for all the architectures that the GNU tools support built in by default, FreeBSD makes a great development system for all sorts of weird (and wonderful?) architectures. I used to build MVME68K code on FreeBSD. Back in the good old days. -- John Birrell
