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.
