The reason that bfd_free_cached_info does nothing is because on elf targets it
is #defined to be _bfd_generic_bfd_free_cached_info which is #defined to be

As a complete hack I tried calling this instead of bfd_free_cached_info:
          bfd_hash_table_free (&current->section_htab);
          objalloc_free ((struct objalloc *) current->memory);

This works. That is the memory use remains relatively constant and the resulting
archive is the byte for byte the same as an unpatched ranlib.

Now obviously this is a hack, we shouldn't be using this target-specific code in
target-independent code like archive.c. Perhaps we could have something along
these lines in bfd_free_cached_info on elf targets.
