The part that jumped out at me was 'file too big', so I did some Googling and found this issue which recommended adding the -Wa,-mbig-obj flag to cmake. I did that by adding it to this line, reran things and got this:

Here, I focused on the string table overflow at offset part, and found this issue and decided to add the -O2 flag to the this line, which worked!
Going to create a PR, but the fix is to update this line to read as follows:
