`std` compilation error when compiling for `wasm32-wasi` with `-C target-feature=+atomics,+bulk-memory`

[tomaka]

In order to reproduce:

cargo new hello-world
cd hello-world
RUSTFLAGS="-C target-features=+atomics,+bulk-memory" cargo +nightly build -Z build-std=std --target=wasm32-wasi

This leads to:
