Isn't this only for cross compilation?

I don't have dh-make installed:

Am I not clear enough? As I said before, some packages use
$host=i486-pc-gnu others $host=i686-unknown-gnu0.3.
And when porting packages it is of large interest to know the variants,
so a common pattern can be used for all cases!

I will use this construct from now on.

Why not propose to introduce the quadruple then!
Adding gnumach or hurd or?
