Different recipes give different store paths. The recipe of cross-building
is quite different from the recipe of native building.

If you expect the cross-built 'hello' to have the same hash as the
natively built, I don't know any trick. They are effectively built
differently, and thus, they have a different store path.

I don't know of any way in nix that can relate cross-built packages with
natively built.
