Delete relocations associatesd with deleted exidx entries.
PR ld/20595
ld * testsuite/ld-arm/unwind-4.d: Add -q option to linker command
line and -r option to objdump command line. Match emitted relocs
to make sure that superflous relocs are not generated.
bfd * elf-bfd.h (struct elf_backend_data): Add
elf_backend_count_output_relocs callback to count relocations in
the final output.
* elf-arm.c (elf32_arm_add_relocation): Deleted.
(elf32_arm_write_section): Move additional relocation to emit_relocs.
(elf32_arm_count_output_relocs): New function.
(emit_relocs): New function.
(elf32_arm_emit_relocs): New function.
(elf32_arm_vxworks_emit_relocs): New function.
(elf_backend_emit_relocs): Updated to use the new functions.
(elf_backend_count_output_relocs): New define.
* bfd/elflink.c (bfd_elf_final_link): Do not add additional_reloc_count
to the relocation count.
(_bfd_elf_link_size_reloc_section): Use callback to count the
relocations which will be in output.
(_bfd_elf_default_count_output_relocs): New function.
* bfd/elfxx-target.h (elf_backend_count_output_relocs): New define.
