[ARC] Refactored location where GOT information is collected.
Change location where GOT information is collected for ARC target, avoiding posible use conflicts of the previous .got field in the symbols hash_entry. bfd/ 2018-03-01 Cupertino Miranda <cmiranda@synopsys.com> * arc-got.h (get_got_entry_list_for_symbol): Changed. * ef32-arc.c (struct elf_arc_link_hash_entry): Moved and changed. (elf_arc_link_hash_newfunc): Changed. (arc_elf_link_hash_table_create): Removed old initializations. (elf_arc_relocate_section, elf_arc_finish_dynamic_symbol): Changed.
