Bug ID: 53546
           Summary: ERROR: ld.so: object XXX from /etc/ld.so.preload
                    cannot be preloaded (wrong ELF class: ELFCLASS64):
                    ignored.
           Product: Wine
           Version: 7.14
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Environment: ArchLinux 5.18.15-arch1-1

Step to Reproduce:

1. Install required packages, `sudo pacman -S wine`, `yay -S
rl_custom_isearch`, the latter will add two lines to `/etc/ld.so.perload`:

```
/usr/lib/librl_custom_isearch.so
/usr/lib/librl_custom_function.so
```

2.

```
❯ wine --version
ERROR: ld.so: object '/usr/lib/librl_custom_isearch.so' from /etc/ld.so.preload
cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.
ERROR: ld.so: object '/usr/lib/librl_custom_function.so' from
/etc/ld.so.preload cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.
wine-7.14
```

The ERROR always occur for any wine's program.

The origin issue is https://github.com/lincheney/rl_custom_isearch/issues/4.

It's not possible to preload 64-bit libraries in a 32-bit binary like wine. You
can safely ignore the warnings.

Thanks. How can I disable the output of these ERROR? I try `export
WINEDEBUG=-all` but useless.

The messages come from ld.so, not Wine. You might be able to mess with ld.so
environment variables (LD_DEBUG?).

I refer https://man7.org/linux/man-pages/man8/ld-linux.so.8.html and try
`export LD_DEBUG_OUTPUT=/tmp`, but it cannot work. The ERROR still occur.
