kclvm-runtime fails to buid on aarch64 about kcl

[Peefy]

Hello @AdmiralNemo. Thank you for your feedback. This may be due to Rust FFI type of core::ffi::c_char varies on different machines, and I will try using the generic fix later to address this issue. #983

Related Issue: kcl-lang/cli#31 and #985

Thanks for the quick response! With the latest commit, I'm seeing some different but related compilation errors:
