@monstercatss yes, that's the case. I have just found though that adding arm64 there just works. I needed to cross compile runtime for arm on arm64 and adding it to the place you've referred to was sufficient to make it work. I'll create a PR with that change soon.
Can you please share the reason why you were interested in it? I am just curious.
