Build fails for aarch64-alpine-linux-musl

aarch64-alpine-linux-musl ターゲットに対して cargo build --release を実行し、src/uu/lsipc/src/semaphore.rs、message_queue.rs、shared_memory.rs で報告されたエラーから着手してください。また、src/uu/blockdev/src/blockdev.rs と src/uu/fsfreeze/src/fsfreeze.rs の ioctl 呼び出し箇所も調査してください。報告された musl 関連のコンパイルエラーが解消され、release ビルドが成功すれば完了です。

Running cargo build --release on the tree results in:
