Apply a workaround to mitigate a quadratic performance hit in the linker when writing out secondary reloc sections.
PR 26406
* elf-bfd.h (struct bfd_elf_section_data): Add
has_secondary_relocs field.
* elf.c (_bfd_elf_copy_special_section_fields): Set the
has_secondary_relocs field for sections which have associated
secondary relocs.
* elfcode.h (elf_write_relocs): Only call write_secondary_relocs
on sections which have associated secondary relocs.
