I've just tried to comment all "-Werror" in Makefile. The kernel is being compiled using "make -j1" without error at the moment..

Removing the option CONFIG_RTL8812AU from kernel config leads to normal compiling without any errors.

I've found the solution and made pull request. It is the same as for rtl8188eu.
