Compilation on Nanopi Neo2 fails for Realtek 8812au

Hi,

I am trying to install the aircrack-ng driver via dkms from over here:

https://github.com/aircrack-ng/rtl8812au

When I change the Makefile to match my processor arm-sun50iw1p1 , I receive these compilation errors and do not know how to fix them.

cat /var/lib/dkms/rtl8812au/5.2.20.2/build/make.log
