bfd_link_hash_table_create is still available.

If you want to continue using bfd_link_hash_table_create, then your
cleanup should run:

  if (abfd->is_linker_output)
    (*abfd->link.hash->hash_table_free) (abfd);

However, I think you're going to be sorely disappointed in the
linker's ability to relocate final linked binaries.
