Linking issue. recipe for vmlinux is failed.

[Saurabh Sakhare]

While compiling the kernel for walleye pixel 2 device. The kernel is compiling perfectly but at the time of link, it's failing the thing I understood is the symbol needed by function cannot be found. 

How can I make it found?

The errors are given below and this undefined reference is showing for every symbol.
