Ian Lance Taylor d3bbad6265 * target-reloc.h (relocate_section): Check the symbol table index
for -1U before setting the local symbol index.

	the local symbol is required.
	* object.h (Symbol_value::is_output_symtab_index_set): New
	function.
	(Symbol_value::may_be_discarded_from_output_symtab): New
	function.
	(Symbol_value::has_output_symtab_entry): New function.
	(Symbol_value::needs_output_symtab_entry): Remove.
	(Symbol_value::output_symtab_index): Make sure the symbol index is
	set.
	(Symbol_value::set_output_symtab_index): Make sure the symbol
	index is not set.  Make sure the new index is valid.
	(Symbol_value::set_must_have_output_symtab_entry): New function.
	(Symbol_value::has_output_dynsym_entry): New function.
	(Symbol_value::set_output_dynsym_index): Make sure the new index
	is valid.
	(Sized_relobj::set_must_have_output_symtab_entry): New function.
	* object.cc (Sized_relobj::do_count_local_symbols): Only discard a
	local symbol if permitted.
	(Sized_relobj::do_finalize_local_symbols): Call
	is_output_symtab_index_set rather than needs_output_symtab_entry.
	(Sized_relobj::write_local_symbols): Call has_output_symtab_entry
	rather than needs_output_symtab_entry.  Call
	has_output_dynsym_entry rather than needs_output_dynsym_entry.
	* arm.cc (Arm_relobj::update_output_local_symbol_count): Call
	is_output_symtab_index_set rather than needs_output_symtab_entry.
	* testsuite/discard_locals_relocatable_test.c: New file.
	* testsuite/discard_locals_test.sh: Test -r.
	* testsuite/Makefile.am (check_DATA): Add
	discard_locals_relocatable_test1.syms,
	discard_local_relocatable_test2.syms.
	(MOSTLYCLEANFILES): Likewise.  Also add
	discard_locals_relocatable_test1.lout and
	discard_locals_relocatable_test2.out.
	(discard_locals_relocatable_test1.syms): New target.
	(discard_locals_relocatable_test.o): New target.
	(discard_locals_relocatable_test1.out): New target.
