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.
In fact, keeping this support around forces correct use of
posix APIs such as e.g. PRIx64 which makes the code base
more future-proof.
