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

首先使用 copilot 重现该故障，并在 Oracle Linux 10 上使用提供的 strace 和 readelf 命令检查 ./copilot 可执行文件。比较已安装的构件在受支持环境中的打包和启动方式；当已安装的 copilot 命令无需直接调用 ld.so 即可正常启动时，即表示完成。
