For FreeBSD systen we have no 32bit arm host users. There may be a few i386
host users left, but they are a tiny sliver of users. The overwhelming bulk
of our users for qemu-system- are on x86-64 or aarch64 hosts.

For bsd-user, there is no 32 bit host support at all. It was dropped as
part of the push to prune old code and upstream.
