With ``qemu-x86_64-static`` from ``qemu-8.1.3-1.fc39``, I can no longer run on the m1 the ``x86_64`` binary created by https://github.com/containers/PodmanHello

If I try with ``qemu-x86_64-static`` from ``qemu-7.2.7-1.fc38`` then this works.

If I build the binary manually on a fc39 x86 system with ``gcc -O2 -static -o podman_hello_world podman_hello_world.c``, then I can also run it successfully with ``qemu-8.1.3-1.fc39``.
It's only the static binary built inside the alpine container which cannot be run on the M1.


Misc tests I ran:

```
$ ./qemu-x86_64-static-8.1.3 podman_hello_world.alpine 
qemu-x86_64-static-8.1.3: /var/roothome/podman_hello_world.alpine: Unable to find a guest_base to satisfy all guest address mapping requirements
  0000000000000000-0000000000000fff
  0000000000400000-00000000004047ef

$ ./qemu-x86_64-static-7.2.7 podman_hello_world.alpine 
!... Hello Podman World ...!
[...]

$ ./qemu-x86_64-static-8.1.3 podman_hello_world.fc39 
!... Hello Podman World ...!
[...]
```

The issue is still present with ``qemu-8.2.0-0.3.rc2.fc40``

I also could not reproduce on ``x86_64`` machines. I just tried it on fc39 installed on non-Apple ``aarch64`` hardware, and I'm seeing the same issue:

```
# rpm -qf /usr/bin/qemu-x86_64-static 
qemu-user-static-x86-8.1.3-1.fc39.aarch64

# qemu-x86_64-static ./podman_hello_world.alpine 
qemu-x86_64-static: /root/podman_hello_world.alpine: Unable to find a guest_base to satisfy all guest address mapping requirements
