build kernel for arm64 - linker ld ignored -z relro

[Milan Buška]

Hello.
I'm compiling the kernel v.5.8.7 on arm64.
This is a compilation in a native environment.
Toolchain:
glibc v. 2.32
binutils v. 2.35
gcc v. 10.2.0

This is the last part of the output after make Image.

The file in which the norelro is declared (probably)
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/arm64/Makefile?h=v5.8.7

Tested on archlinuxarm last rootfs.

Best regards
Milan
