To Reproduce

Run cargo clippy

Expected behavior

No response

Additional context

May pass CI because the clippy roles are override on linux

[target.x86_64-unknown-linux-gnu]
rustflags = [
    "-Clink-arg=-fuse-ld=lld",
    "-Clink-arg=-Wl,--no-rosegment",
    "-Ctarget-feature=+avx2",
    "--cfg",
    "tokio_unstable",
]

# Remove "-Ctarget-feature=+neon" if your aarch64 target does not support NEON vector extensions
[target.aarch64-unknown-linux-gnu]
rustflags = [
    "-Clink-arg=-fuse-ld=lld",
    "-Clink-arg=-Wl,--no-rosegment",
    "-Ctarget-feature=+neon",
    "--cfg",
    "tokio_unstable",
]

I guess the rustflags under [build] was overrided in [target.x86_64-unknown-linux-gnu] and [target.aarch64-unknown-linux-gnu]...

I can take it if nobody is working on this
