What is this lint about

Previously inputs for many built-in attributes weren't validated and nonsensical attributes like #[no_std(arbitraty, string = "foo")] were accepted.
#57321 introduced a check for top-level shape (#[attr] vs #[attr(...)] vs #[attr = ...]) for built-in attributes that produces an error by default, but produces a warning for incorrect attribute forms available on stable that were actually encountered in practice (during crater run).
Currently the list is

#[doc]
#[ignore(...)]
#[inline = "..."]
#[link]
#[link = "..."]

, but it can be extended if more regressions are reported.

How to fix this warning/error

Use one of the correct attribute forms suggested by the compiler.

Fix build warning on #[ignore] attrbute
3770d7c 
The full warning:

    warning: attribute must be of the form `#[ignore]` or `#[ignore = "reason"]`
    = note: #[warn(ill_formed_attribute_input)] on by default
    = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
    = note: for more information, see issue #57571 <rust-lang/rust#57571>

Remove #[link] attributes

They cause the following warnings:
warning: attribute must be of the form `#[link(name = "...", /*opt*/ kind = "dylib|static|...",
                                               /*opt*/ cfg = "...")]`
 --> /tmp/coreaudio-sys/target/x86_64-apple-darwin/debug/build/coreaudio-sys-0d8fd082e359c2ec/out/coreaudio.rs:3:1

  = note: #[warn(ill_formed_attribute_input)] on by default
  = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
  = note: for more information, see issue #57571 <rust-lang/rust#57571>

And they are actually redundant with the cargo:rustc-link-lib lines the
build script prints already.
