(As I was in To) I do not understand the question.

One idea is if you want symbols from Linux kernel, look for file 'vmlinux'
(if it is built in kernel config with debug symbols).

GDB is userland process, it only uses system calls of Linux kernel (if you
mean Linux kernel).  GDB is in fact unrelated to kernels.
