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.

* 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-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.
