描述

We could make cross compilation a lot easier using default.nix, as it can take the systems as parameters

研究方向
The issue was proposed by @roberth in a comment on issue #8556, suggesting that cross compilation can be facilitated by using `default.nix` to take system parameters. To implement this, one would need to examine the current build system in the Nix repository, particularly the existing `default.nix` and any cross compilation related configurations. The goal is to simplify cross compilation by leveraging Nix's ability to parameterize systems in the default Nix expression.
