| Add new `eval-system` setting | 4093 |
Add a new eval-system option.
Unlike system, it just overrides the value of builtins.currentSystem.
This is more useful than overriding system, because you can build these derivations on remote builders which can work on the given system.
In contrast, system also effects scheduling which will cause Nix to build those derivations locally even if that doesn't make sense.
eval-system only takes effect if it is non-empty.
If empty (the default) system is used as before, so there is no breakage.
