Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e78a588b595dc8d4d57fdd6369325ea5c0b690a5

--------------------------------

[ Upstream commit 27f2a4db ]

GDB produces the following warning when debugging kernels built with
CONFIG_RELR:

BFD: /android0/linux-next/vmlinux: unknown type [0x13] section `.relr.dyn'

when loading a kernel built with CONFIG_RELR into GDB. It can also
prevent debugging symbols using such relocations.

Peter sugguests:
  [That flag] means that lld will use dynamic tags and section type
  numbers in the OS-specific range rather than the generic range. The
  kernel itself doesn't care about these numbers; it determines the
  location of the RELR section using symbols defined by a linker script.
