Attributes applied to macro calls are not checked

[JonathanBrouwer]

I tried this code:

macro_rules! bar {
    () => {};
}

#[link(this, is, not, checked)]
bar!();

I expected this to error, but it does not.
All attributes (this is not specific to link) applied to macro calls are not checked.
It does provide the warning:

warning: unused attribute `link`
 --> src/main.rs:5:1

5 | #[link(this, is, not, checked)]

Oh actually this is not specific to macro calls, this just happens to all attributes applied to non-correct targets
