How to build NVRC locally?

Background

In order to debug NVRC panic issue for 4 or 8 GPU passthrough scenario，I tried to increase timeout value(timeout waiting for: Local RPC services initialized) and build NVRC locally, the build process is fine, but after I replace NVRC binary in kata 3.32.0 guest image with my local built one, vm booting process always failed due to init process issue, I tried different building machines and different building OS distros, no lucky.
And I can boot vm successfully by replacing NVRC binary with the github released artifacts.

Building command

# for v0.1.5 version
./scripts/build-release.sh x86_64-unknown-linux-musl

# for v0.1.4 version
cargo build --release --target x86_64-unknown-linux-musl

Boot failed logs for Ubuntu 25.04 building machine

Start with scripts/build-release.sh and the cargo build command for x86_64-unknown-linux-musl, then compare the resulting NVRC file type with the Ubuntu and CentOS examples. Reproduce the guest boot using the locally built binary and inspect the init segfault or dynamic-linking failure; done means the local build produces an artifact that boots successfully in the reported Kata guest scenario.
