 But then host (correctly) defaults to build but host_alias (incorrectly) 
defaults to host.  I mean the current dependency between variables in
autoconf is as follows ("(sub)" meaning passing through config.sub): 

                guess
                   |
override -(sub)-+  |
|               |  |
v               v  v
build_alias <-- build
                   |
override -(sub)-+  |
|               |  |
v               v  v
host_alias <--- host
                   |
override -(sub)-+  |
|               |  |
v               v  v
target_alias <- target

And I would like to see it as follows:

            guess
            |
            v
override -> build_alias --(sub)-> build
            |
            v
override -> host_alias ---(sub)-> host
            |
            v
override -> target_alias -(sub)-> target

I think it makes sense and the dependencies seem even simpler.
