(mips_elf_link_hash_newfunc): Update accordingly. (mips_elf_link_hash_table): Remove "computed_got_sizes" and add "lazy_stub_count". (_bfd_mips_elf_link_hash_table_create): Update accordingly. (mips_elf_output_extsym): Use hd->needs_lazy_stub to detect cases where a lazy stub is being used. (mips_elf_sort_hash_table_f): Use h->root.forced_local instead of h->forced_local. (mips_elf_record_global_got_symbol): Use _bfd_elf_link_hash_hide_symbol instead of _bfd_mips_elf_hide_symbol. Do not increment local_gotno here. (mips_elf_allocate_dynamic_relocations): Move before new first use. (mips_elf_check_recreate_got, mips_elf_recreate_got): New functions. (mips_elf_resolve_final_got_entries): Move earlier in file. Make at most two passes over the hash table. Use mips_elf_check_recreate_got to see if there are any indirect or warning entries and mips_elf_recreate_got to create a new GOT without them. Return a boolean success value. (mips_elf_count_forced_local_got_entries): New function. (mips_elf_make_got_per_bfd): Check h->root.forced_local instead of h->forced_local.

(mips_elf_multi_got): Fix formatting. Use mips_elf_forbid_lazy_stubs instead of mips_elf_set_no_stub. Move the code that sets global offsets and allocates dynamic relocations from the main _bfd_mips_elf_size_dynamic_sections loop to here.

(mips_elf_estimate_stub_size): New function, split out from _bfd_mips_elf_always_size_sections. Call mips_elf_resolve_final_got_entries earlier. Count the number of forced-local entries. Do not add stub sizes to loadable_size; after this patch, the stub sizes are already included in the main estimate. Allocate dynamic relocations here rather than in the main _bfd_mips_elf_size_dynamic_sections loop. (mips_elf_estimate_stub_size): New function, split out from _bfd_mips_elf_always_size_sections.
