That's theoretically a good idea, but I think I'd rather do it the other
way round: include i386-softmmu.mak in the x86_64 config file.
Rationale: x86_64 is supposed to be a superset of i386, not the other
way round, so when we will ever get a CONFIG_SWITCH_FOR_X86_64_ONLY,
it's easier to handle if the includes are done the other way round.

And that's also how we do it in aarch64-softmmu.mak an ppc64-softmmu.mak.
