only if info->emit_hash, create .gnu.hash section if
info->emit_gnu_hash.

that and NSYMS as arguments. Use bed->s->sizeof_hash_entry
instead of bed->s->arch_size / 8. Fix .hash size estimation.
When not optimizing, use the number of hashed symbols rather than
dynsymcount.

and ADD DT_GNU_HASH if info->emit_gnu_hash.

adjust compute_bucket_count caller. Create and populate .gnu.hash
section if info->emit_gnu_hash.

finfo->hash_sec != NULL.
