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.
