Don't call bfd_link_hash_table_free 

Freeing the linker hash table is a royal pain.  It can't be freed
before the _bfd_write_contents call in bfd_close, because some target
bfd_write_contents functions access the hash table.  It can't be freed
after bfd_close either, since bfd_alloc memory holding side data
structures disappears (PR17047).  Clearly the only place it can be freed
is actually in bfd_close.  This patch doesn't do that, but kills off
the existing means of freeing the hash table via a bfd target xvec call.
