ARM: 9038/1: Link with '-z norelro'
When linking a multi_v7_defconfig + CONFIG_KASAN=y kernel with LD=ld.lld, the following error occurs: $ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- LLVM=1 zImage ld.lld: error: section: .exit.data is not contiguous with other relro sections LLD defaults to '-z relro', which is unneeded for the kernel because program headers are not used nor is there any position independent code generation or linking for ARM. Add '-z norelro' to LDFLAGS_vmlinux to avoid this error.
