The chinese seem to have built a native opnwrt for Slate 7 GL-BE3600 but with heavy mods

[AskAlice]

So i noticed GitHub - wukongdaily/be3600: 该项目可以让BE3600路由器在不刷机情况下,一键变成类似iStoreOS风格 · GitHub as well as iStoreOS · GitHub

another chinese git author even has a repo for a custom LCD mod for the flint 7 GitHub - linkease/lcdsimple-be3600 · GitHub

So how are they building openwrt for this target this given the toolchain has been made private?

I found a tar of istoreos for the gl-be3600 on the device folder of GitHub - linkease/firmware-data · GitHub

Hi,

The first GitHub link is only a script for one-click installation of an iStoreOS-like theme and other plugins. It is still running the stock GL.iNet firmware.

As for the second GitHub link for the LCD, since the BE3600 uses the aarch64 architecture, you can generally use any toolchain you prefer to compile the software, except for kernel-related components. You only need to make sure that the architecture and dependencies match.
