Put .dynbss and .rel.bss shortcuts in main elf hash table
Also, create .rel{,a}.bss for PIEs on all targets, not just x86. * elf-bfd.h (struct elf_link_hash_table): Add sdynbss and srelbss. * elflink.c (_bfd_elf_create_dynamic_sections): Set them. Create .rel.bss/.rela.bss for executables, both PIE and non-PIE. * elf32-arc.c (struct elf_arc_link_hash_table): Delete srelbss. Use ELF hash table var throughout. * elf32-arm.c (struct elf32_arm_link_hash_table): Delete sdynbss and srelbss. Use ELF hash table vars throughout. * elf32-hppa.c (struct elf32_hppa_link_hash_table): Likewise. * elf32-i386.c (struct elf_i386_link_hash_table): Likewise. * elf32-metag.c (struct elf_metag_link_hash_table): Likewise. * elf32-microblaze.c (struct elf32_mb_link_hash_table): Likewise. * elf32-nios2.c (struct elf32_nios2_link_hash_table): Likewise. * elf32-or1k.c (struct elf_or1k_link_hash_table): Likewise. * elf32-ppc.c (struct ppc_elf_link_hash_table): Likewise. * elf32-s390.c (struct elf_s390_link_hash_table): Likewise. * elf32-tic6x.c (struct elf32_tic6x_link_hash_table): Likewise. * elf32-tilepro.c (struct tilepro_elf_link_hash_table): Likewise. * elf64-ppc.c (struct ppc_link_hash_table): Likewise. * elf64-s390.c (struct elf_s390_link_hash_table): Likewise. * elf64-x86-64.c (struct elf_x86_64_link_hash_table): Likewise. * elfnn-aarch64.c (struct elf_aarch64_link_hash_table): Likewise. * elfnn-riscv.c (struct riscv_elf_link_hash_table): Likewise. * elfxx-mips.c (struct mips_elf_link_hash_table): Likewise. * elfxx-sparc.h (struct _bfd_sparc_elf_link_hash_table): Likewise. * elfxx-sparc.c: Likewise. * elfxx-tilegx.c (struct tilegx_elf_link_hash_table): Likewise. * elf32-arc.c (arc_elf_create_dynamic_sections): Delete. (elf_backend_create_dynamic_sections): Use base ELF version. * elf32-microblaze.c (microblaze_elf_create_dynamic_sections): Delete. (elf_backend_create_dynamic_sections): Use base ELF version. * elf32-or1k.c (or1k_elf_create_dynamic_sections): Delete. (elf_backend_create_dynamic_sections): Use base ELF version. * elf32-s390.c (elf_s390_create_dynamic_sections): Delete.

(elf_backend_create_dynamic_sections): Use base ELF version. * elf64-s390.c (elf_s390_create_dynamic_sections): Delete. (elf_backend_create_dynamic_sections): Use base ELF version. * elf32-tilepro.c (tilepro_elf_create_dynamic_sections): Remove extraneous tests. * elfnn-aarch64.c (elfNN_aarch64_create_dynamic_sections): Likewise. * elfxx-mips.c (_bfd_mips_elf_create_dynamic_sections): Likewise. * elfxx-tilegx.c (tilegx_elf_create_dynamic_sections): Likewise. * elf32-i386.c (elf_i386_create_dynamic_sections): Don't create ".rel.bss" for executables. * elf64-x86-64.c (elf_x86_64_create_dynamic_sections): Don't create ".rela.bss" for executables. * elf32-nios2.c (nios2_elf32_create_dynamic_sections): Don't ignore return status from _bfd_elf_create_dynamic_sections.
