This fixed wasm checkasm failure
$ wasm-tools validate tests/checkasm/checkasm
error: wasisdk://v25.0/build/sysroot/wasi-libc-wasm32-wasip1-threads/libc-top-half/musl/src/stdio/__stdio_close.c:24:9 function `__stdio_close` failed to validate
Caused by:
0: func 4581 failed to validate
1: type mismatch: expected i32 but nothing on stack (at offset 0x43b770)
Since close is declared as static function, it's more like a bug
in wasi sdk, but we can workaround it easily.
