So just removing the ONLY_FOR_ARCHS is not good enough since these ports will not run on all architectures that have a working linux_base; amd64 is a special case here since it's largely backwards compatible with i386. What should probably be done is to add amd64 to ONLY_FOR_ARCHS when those ports are tested and confirmed to work on amd64.
