Failure compiling box64 on Pi 4 x64
Hello,

So I am following these steps here in order to compile the box64:

https://pimylifeup.com/raspberry-pi-x64/

When I attempt to run the "make" command, it just fails with the following regarding INT128 (warning its quite a large output, ill submit the whole thing via txt file):

I confirmed that the OS is 100% 64-bit aarch64.

Any ideas on how I can get this to compile? It might be worth noting that I just did the x86 using that sites other guide, but then it told me to move to x64 and install it as well, x86 compiling went fine so I am at a loss here.

Thank you!
