could not document `std` for wasm32-unknown-unknown

[walkingeyerobot]

I have my config.toml file:

changelog-seen = 2
[install]
prefix = "/home/walkingeye/rust-test"
[build]
target = ["wasm32-unknown-unknown", "x86_64-unknown-linux-gnu"]

Everything builds fine, but when I run ./x.py install, I get the following error:

error: could not document `std`

The install process does succeed if I change the target array in config.toml to target = ["x86_64-unknown-linux-gnu"].
