Motivation for this change
Allows
buildRustCrate
to be used to cross-compile Rust crates. This PR implements the changes that are needed on the nixpkgs side, but neithercrate2nix
norcarnix
(haven't tested, but a quick look at the code makes me think it doesn't) support cross-compilation. I have a WIP patch forcrate2nix
to fix this.Things done
