Cannot compile 'wasm-bindgen-futures' due conditional dependency on target feature

[TheNeikos]

I am currently trying to build a crate that as one of its transitive dependencies wasm-bindgen-futures and from this code: https://github.com/rustwasm/wasm-bindgen/blob/master/crates/futures/Cargo.toml#L18 it generates the following code:

target = { target, features }: (target."feature" == "atomics");

This then errors with: attribute 'feature' missing.

It is similar to #37 but it uses target_feature here instead of just target

I have a similar problem (target = { target, features } line):

      "aes" = rec {
        crateName = "aes";
        version = "0.3.2";
        edition = "2015";
        sha256 = "1j90iwpax0y1dqq14i8y9xgpcnnlgnljwkxg3mhzrralwf7ivssl";
        authors = [
          "RustCrypto Developers"
        ];
        dependencies = [
          {
            name = "aes-soft";
            packageId = "aes-soft";
            target = { target, features }: (!((target."feature" == "aes") && (target."feature" == "sse2") && ((target."arch" == "x86_64") || (target."arch" == "x86"))));
          }

Adding a feature = "" in defaultTarget is a hotfix that worked for me.

Merged this #142

I hope it helps!
