Hi there,
@mistfire
No, SliTaz Next doesn't support multilib. When I made it back in time, I followed Linux From Scratch "recipes". LFS doesn't support multilib, so SliTaz doesn't support it too.
Sorry, the development of SliTaz Next stopped. It's hard to non-programmer to follow all the updates on the one hand, and to find reliable patches to the legacy on the other hand. About a week ago I tried to follow LFS to update the toolchain. No luck. Every time gcc failed to make the new version of itself after long, more than a hour, runs.
I think I can't cope with the software. And I think I should not repeat the things already resolved on other Linux distributions by myself. I think it will better if I'll use some other small Linux distro, most-least actively developed, with good package base and without systemd :) Well, I think I'll use its packages to make SliTaz clone (like made tower using cubes) and will make SliTaz native packages to it if I will need them.
I think Adelie Linux is a good candidate. It is Musl based instead of widespread Glibc, but I think it's not the problem. Adelie actively updated providing packages for many platforms. Packages are well splitted. I hope I'll find some time sometimes to test it :)

There a weird system on the cook server, but I think we can't make it better. Direct link will not work, the button will be hidden. Your web browser should send the server correct HTTP REFERER. In few words, it contains the URL address of the page you leave. So, you should 1) open any relevant page on the cook server, and 2) click the link on that page to go to gtk2 page. Better if you 1) just search for gtk2, and then 2) click on gtk2 link on the search page.
It is not 100% guarantee against the malicious (or curious) web bots that may click on the "Recook" buttons and to load cook server with unwanted work. But it works and no false triggerings since there.
