Kernel execve returns ENOEXEC but ld.so runs fine — readelf attached — Oracle Linux 10 — x86_64

Describe the bug

I was unable to run the Github copilot CLI on Oracle Linux 10 when installing though npm. After troubleshooting, I discovered that I am able to run the copilot binary when forcing it to execute via ld directly, but unable when executing the binary normally.

Affected version

GitHub Copilot CLI 1.0.78

Steps to reproduce the behavior

1. Run `npm install -g @github/copilot
2. Run copilot

Expected behavior

Copilot launches normally

まず copilot で失敗を再現し、Oracle Linux 10 上で提供されている strace と readelf コマンドを使って ./copilot 実行ファイルを調べます。サポート対象の環境間で、インストールされたアーティファクトがどのようにパッケージ化され、起動されるかを比較します。完了の条件は、インストールされた copilot コマンドが ld.so を直接呼び出さずに正常に起動することです。
