Multilib Alpine (ex: both 32-bit and 64-bit libraries)

One thing I JUST noticed was that Alpine Linux doesn't have the split library setup I'm used to with other platforms (ex: /usr/lib32, /usr/lib/libx32, or the more generic /usr/lib/i396-linux-gnu /usr/lib/x86_64-linux-gnu)

Are there any guides for say installing wine in 32-bit mode on a machine with 64-bit as the install?

I suspect a chroot/docker/LXC may be the current answer with binding /home across (and perhaps /etc and /var)... but I was kinda hoping there'd be a simpler more integrated way.

Currently my machine I'm using Alpine for has no need for 32-bit applications running (it's primarily a server with the occasional use as test build machine) but want to be ready in case it comes to bear that I must have 32-bit binary support.
