Building/testing a crate with features seems broken

[pitdicker]

On the CI for Rand we have the following test for testing with stdweb:

cargo web test --target wasm32-unknown-unknown --nodejs --features=stdweb

Since yesterday it fails with the error from https://internals.rust-lang.org/t/help-us-test-the-breaking-bug-fix-to-cargo-features/7317:

error: error: cannot specify features for more than one package

Using --all-features instead works for rand.

Hmm... looks like this is an issue with cargo itself. If you run this it will also generate the same error: cargo metadata --features stdweb

I've created an issue here: rust-lang/cargo#5439
