There is a build issue with LD segmentation fault, while CONFIG_LD_DEAD_CODE_DATA_ELIMINATION is not enabled, as bellow. scripts/link-vmlinux.sh: line 49: 3796 Segmentation fault (core dumped) ${ld} ${ldflags} -o ${output} ${wl}--whole-archive ${objs} ${wl}--no-whole-archive ${wl}--start-group ${libs} ${wl}--end-group ${kallsymso} ${btf_vmlinux_bin_o} ${ldlibs} The error occurs in older versions of the GNU ld with version earlier than 2.36. It makes most sense to have a minimum LD version as a dependency for HAVE_LD_DEAD_CODE_DATA_ELIMINATION and eliminate the impact of ".reloc .text, R_ARM_NONE, ." when CONFIG_LD_DEAD_CODE_DATA_ELIMINATION is not enabled.
