This patch will break ld -r, since you will be adjusting relocs
against section symbols twice. The following code in elfnn-aarch64.c
needs adjusting too.
if (info->relocatable)
{
/* This is a relocatable link. We don't have to change
anything, unless the reloc is against a section symbol,
in which case we have to adjust according to where the
section symbol winds up in the output section. */
if (sym != NULL && ELF_ST_TYPE (sym->st_info) == STT_SECTION)
rel->r_addend += sec->output_offset;
continue;
}
