Add tls_ldm_got + uion to track TLS GOT references. Add sym_sec to cache + mappings from local sym to section. + (link_hash_newfunc): New function. + (sparc64_elf_bfd_link_hash_table_create): Rename to + sparc64_elf_link_hash_table_create for consistency. + Pass link_hash_newfunc to _bfd_elf_link_hash_table_init. + (sparc64_elf_create_dynamic_sections): Initialize new section + members of sparc64_elf_link_hash_table. Only init srelbss + if not-shared. + (sparc64_elf_copy_indirect_symbol, sparc64_elf_tls_transition): + New functions. + (SPARC_NOP): Define. + (sparc64_elf_build_plt, sparc64_elf_plt_entry_offset, + sparc64_elf_plt_ptr_offset): Delete. + (sparc64_plt_entry_build): New function to build PLT entries + gradually instread of all at once at the end of linking. + (sparc64_elf_check_relocs): Delete dynobj, sgot, and srelgot + local vars. Get them from sparc64_elf_hash_table instead. + Check early on if r_symndx is in bounds. Handle TLS transitions. + Account for TLS GOT references and DF_STATIC_TLS, as needed. + For TLS relocs, record the tls_type in either + sparc64_elf_local_got_tls_type or sparc64_elf_hash_entry as + appropriate. For R_SPARC_TLS_{GD,LDM}_CALL, emit a reference + to the __tls_get_addr symbol. For PLT relocs, track references + via h->plt.refcount. When R_SPARC_{PC10,PC22,PC_HH22,PC_HM10, + PC_LM22} and h not-NULL, set h->non_got_ref. For global data + symbol references, count the number of relocations needed for + that symbol. For default switch case, don't error, this lets + the TLS relocs not explicitly handled by this function get + accepted. + (sparc64_elf_gc_mark_hook, sparc64_gc_sweep_hook): New functions. + (sparc64_elf_adjust_dynamic_symbol): Remove dynobj local var, get + it from sparc64_elf_hash_table. Store the real PLT offset + in h->plt.offset, and build PLT entries one at a time.

Handle TLS + relocations and refcounting in main relocation loop. + (sparc64_elf_finish_dynamic_symbol): Use + sparc64_elf_link_hash_table. Build PLT entries as we see + them. Handle TLS GOT relocations. + (sparc64_elf_finish_dynamic_sections): Get sgot and dynobj + from sparc64_elf_hash_table.
