Confusing warning when using `link_section` on `extern static`

Code

unsafe extern {
    #[unsafe(link_section = ".buffer")]
    pub static mut a: [u8; 1024];
}

Current output

warning: attribute should be applied to a function or static
  --> <source>:10:5
   |
10 |     #[unsafe(link_section = ".buffer")]
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
11 |     pub static mut a: [u8; 1024];
   |     ----------------------------- not a function or static
   |
   = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
   = note: `#[warn(unused_attributes)]` on by default

warning: 1 warning emitted

Desired output

Not sure if the attribute should be allowed on extern statics... but if the answer is no, the warning should still be reworded to avoid saying that an extern static is "not a static".

Rationale and extra context

No response

Other cases

Rust Version

Rust 1.84

Anything else?

Example due by @moridinga

Start by reproducing the Rust 1.84 example with an unsafe extern static and capture the current warning. Trace the compiler diagnostic for link_section and check how extern statics are classified. Done means determining whether the attribute is allowed and ensuring any rejection or warning describes the declaration accurately.
