The arm32 platform literally does not support the memory primitives needed to safely to RDMA. If we enable the support, and someone uses it, there is nothing we can do to prevent them running the risk of memory corruption. So we probably need to exclude arm32 from all these packages, or conditionally make the packages exclude RDMA support on arm32.
