Closed issue by Anachron on void-packages repository

https://github.com/void-linux/void-packages/issues/34988

Description:
I'm currently testing a `i686` repo on `/r32` with the following.

`wine` needs an ugly wrapper so far:

```
#!/bin/sh

export WINEDLLPATH="/lib/wine/i386-unix"
sudo -E chroot /r32 "/usr/libexec/wine/wine" "${@}"
```

`/usr/libexec/wine/wine` needs to be symlinked to this script in order for `/bin/wine` (see https://github.com/void-linux/void-packages/blob/master/srcpkgs/wine/files/wine) to find it. 
I've put `/usr/bin/chroot /r32` inside my `sudoers` file to not need to type any password for chroots on this path.

The tool `bottles` (see https://github.com/void-linux/void-packages/pull/27066) can now find and launch wine on `32bit`:

```
$ bottles
2022-01-11 09:13:38 INFO: Dxvk found: [dxvk-1.9.2]
2022-01-11 09:13:38 INFO: Vkd3d found: [vkd3d-proton-2.5]

|caffe-6.23]
2022-01-11 09:13:41 INFO: Bottles gestartet!
```

For convinience I wrote a little `xp32` helper to handle packages inside the `x86` chroot:

```sh
#!/bin/sh

export XBPS_ARCH="i686"

pl=$(xbps-query -p repository -s multilib | sed 's/-[^:-]*: .*//g')
test -z "${pl}" || {
  printf '%s\n' "${pl}" > xp32-pkg.list
  xbps-remove ${pl}
}

test -d "/r32" || {
  mkdir -v /r32
  repo="http://alpha.de.repo.voidlinux.org/current"
  xbps-install -S -R "${repo}" -r /r32 base-system || rm -rfv /r32
  unlink /lib32
  rm -rf /usr/lib32
  test -L /lib32 || ln -s /r32/lib /lib32
  test -L /usr/lib32 || ln -s /r32/lib /usr/lib32
  rm /r32/dev/null
  rmdir /r32/{dev,home,mnt,media,proc,sys,tmp}
}

case "${1}" in
  c|reconf) shift; xbps-reconfigure -r /r32 "${@}";;
  d|pkgdb) shift; xbps-pkgdb -r /r32 "${@}";;
  i|install) shift; xbps-install -r /r32 "${@}";;
  q|query) shift; xbps-query -r /r32 "${@}";;
  r|remove) shift; xbps-remove -r /r32 "${@}";;
  w|wine)
    shift
    test -e /r32/bin/wine || xbps-install -r /r32 wine
    ln -vs <PATH-TO-WINEWRAPPER> /usr/libexec/wine/wine
    ;;
esac
```

(Don't blindly run this, it will eat you alive)

This is a WIP.
