I feel like we should have separate deprecation entries for the

although they're related they are independant features with
differing impact. eg removing qemu-system-i386 affects all
host architectures, not merely 32-bit x86 host, so I think we
can explain the impact more clearly if we separate them.
Removing qemu-system-i386 seems ok to me - I think qemu-system-x86_64 is
a superset.
Removing support for building on 32 bit systems seems like a pity - it's
one of a small number of ways to run 64 bit binaries on 32 bit systems,
and the maintainance overhead is quite small.
It's not that small. It only works for single-threaded system mode. It silently does not
honor atomicity for user-only mode, which is perhaps worse not working at all.
