Creating musl native on ARM64 runner is not working

[scibaric]

  steps:
      - uses: actions/checkout@v3
      - name: Set up JDK 17
        uses: graalvm/setup-graalvm@v1
        with:
          java-version: '17.0.7'
          version: 'latest'
          distribution: 'graalvm'
          native-image-musl: 'true'
          github-token: ${{ secrets.GITHUB_TOKEN }}
          cache: 'maven'

Fails on both build-jet ARM64 machines and private ARM64 runner and according to log from pipeline it fails due to wrong architecture.

If you take a closer it looks like it's downloading x86_64-linux-musl-native binary.

Thanks for raising this, @scibaric. According to the docs, static linking is not yet supported on ARM64. We should probably print an appropriate error message, when the musl feature is used on non-AMD64 machines.

I didn't know about it 😄 , thanks for taking time and pointing it out. Good luck!
