Something that nobody pointed out is that sometimes you can have
zero-length structures these days. E.g. if you have a struct
containing a few spinlocks in the Linux kernel, it will be zero length
when built on UP targets. I doubt if QEMU has any such structures,
but it's the sort of thing that shouldn't break
qemu_malloc(sizeof(some_type)).
