Hello! This is my first post so please forgive me if I did not write this concisely enough

I am attempting to port Halium-7.0 for the Amazon Fire HD 8 (2018 model, 16gb model, Codename: karnak). I have adapted the device, common, kernel and vendor trees from here. I am keeping track of all the changes I made over on my own github in the following repositories:

Device Tree
Common Tree
Kernel Tree
Vendor Tree

The error: https://del.dog/lofudanaco.txt

What I've tried to do so far: I've come across this article that claims the issue is with the C compiler itself, providing some code to potentially fix the bug, however, I have doubts as to the actual nature of the problem and whether this solution is relevant to my issue or not. Any help is appreciated. TIA!
