OpenRISC BFD fixups for Glibc:

  or1k: Fix static linking when with .rela.got relocations
  or1k: Fix dynamic TLS symbol flag
  or1k: Add TLS mask to handle multiple model access
  or1k: Fix issue with multiple PCREL relocations
  or1k: TLS offset to use tcb size and section alignment
  or1k: refactor: Rename p to sec_relocs
  or1k: refactor: Rename s to sgot and splt
  or1k: Add dynamic flag to tpoff

bfd	* elf32-or1k.c (or1k_elf_finish_dynamic_symbol): Rename srela
	to relgot.
	(or1k_elf_relocate_section): Access srelgot via
	htab->root.srelgot.  Add assertions for srelgot->contents.
	Introduce local variable for srelgot to not reuse global
	sreloc.
	(or1k_elf_relocate_section): Fixup dynamic symbol detection.
	(or1k_set_got_and_rela_sizes): New function.
	(or1k_initial_exec_offset): New function.
	(TLS_GD, TLS_IE, TLS_LD, TLS_LE): Redefine macros as masks.
	(or1k_elf_relocate_section): Allow for TLS to handle multiple
	model access.
	(or1k_elf_check_relocs): Use OR to set TLS access.
	(allocate_dynrelocs): Use or1k_set_got_and_rela_sizes to set
	sizes.
	(or1k_elf_size_dynamic_sections): Use
	or1k_set_got_and_rela_sizes to set sizes.
	(or1k_elf_relocate_section): Fixup PCREL relocation calculation.
	(TCB_SIZE): New macro.
	(tpoff): Use TCB_SIZE and alignment to calculate offset.
	(allocate_dynrelocs, readonly_dynrelocs, or1k_elf_check_relocs)
	(or1k_elf_size_dynamic_sections): Rename p to sec_relocs.
	(allocate_dynrelocs): Rename s to splt or sgot based on usage.
	(tpoff): Add dynamic boolean argument.
	(or1k_elf_relocate_section): Pass dynamic flag to tpoff.
