Android Kernel Building Fails

Hello,

I am trying to compile a Kernel for my Device Mi 9T Pro (raphael), but everytime it comes to compile the kernel it fails.
I used the guide from Nathan Chance on XDA, but even when I go step by step, it doesn't work.
The first point is, that it fails to properly use a parent directory.
Due to the CAF Kernel nature I need to specify an output directory.

I am using this repository:
https://github.com/UtsavBalar1231/kernel_xiaomi_raphael

This is what needs to be done:

mkdir -p out
make O=out distclean
make O=out mrproper
make O=out raphael-stock_defconfig
make O=out -j16

This is what I do:

##Going into the kernel source directory and setting the variables

export CROSS_COMPILE=/home/user/Toolchains/gcc-7.5.0/bin/aarch64-linux-gnu-

export ARCH=arm64 && export SUBARCH=arm64

##Creating a parent directory
mkdir -p out

##Setting up the directory

make O=out clean
