tile: Mark __tls_get_addr in gc_mark_hook
TLS_GD_CALL relocations implicitly reference __tls_get_addr. Since elf_gc_mark_hook is called before check_relocs now, we need to call _bfd_generic_link_add_one_symbol to mark __tls_get_addr for garbage collection. * elf32-tilepro.c (tilepro_elf_gc_mark_hook): Call _bfd_generic_link_add_one_symbol to mark __tls_get_addr. * elfxx-tilegx.c (tilegx_elf_gc_mark_hook): Likewise.
