[Bug]: debuggers do not work under amd64

### I have done the following

- [x] I have searched the existing issues
- [ ] If possible, I've reproduced the issue using the 'main' branch of this project

### Steps to reproduce

1. container run -a amd64 -it fedora bash
2. yum update
3. yum install gdb
4. gdb /bin/true
5. (gdb) run

```
(gdb) run
Starting program: /usr/bin/true
warning: linux_ptrace_test_ret_to_nx: Cannot PTRACE_GETREGS: Input/output error
warning: linux_ptrace_test_ret_to_nx: PC 0x99 is neither near return address 0x7ffff8f14000 nor is the return instruction 0x555555928d32!
Couldn't get CS register: Input/output error
```

the same with lldb, it even core dumps

### Current behavior

They fail to work.

### Expected behavior

GDB and LLDB are expected to work. Actually, the problem is wider - I am getting `illegal hardware instruction` but I can't debug it as GDB and LLDB do not work.

### Environment

```markdown
- OS: Darwin 24.6.0 Darwin Kernel Version 24.6.0: Mon Aug 11 21:16:30 PDT 2025; root:xnu-11417.140.69.701.11~1/RELEASE_ARM64_T8132 arm64
- Xcode: version: 26.0.0.0.1.1757719676
- Container:

### Relevant log output

```shell
(gdb) run

```

### Code of Conduct

- [x] I agree to follow this project's Code of Conduct

Start by reproducing the amd64 Fedora container case with the listed container, gdb, and lldb commands, then investigate how debugger support behaves for amd64 containers on Apple silicon. Done means gdb and lldb run the sample program without the reported register errors or core dump, and the illegal-instruction failure can be debugged.
