I didn't actually... could be considered in preparation of supporting 
GNU hash style.

Anyway, looking at the _dl_add_elf_hash_table, there is a null check for 
the dynamic_info[DT_HASH],
that, should be alway not null, being initialized by 
"_dl_parse_dynamic_info", so for coherence I added that check

Discard this patch if you think currently not pointless.
