Add support for -pie.
* options.h (class General_options): Add -pie and --pic-executable. (General_options::output_is_position_independent): Test -pie. (General_options::output_is_executable): Return true if not shared and not relocatable. (General_options::output_is_pie): Remove. * options.cc (General_options::finalize): Reject incompatible uses of -pie. * gold.cc (queue_middle_tasks): A -pie link is not static. * symtab.h (Symbol::needs_plt_entry): Return false if -pie. * symtab.cc (Symbol::final_value_is_known): Return false if output_is_position_independent. * layout.cc (Layout::set_segment_offsets): Start at address 0 if output_is_position_independent. * output.cc (Output_file_header::do_sized_write): Use ET_DYN if output_is_position_independent. * i386.cc (Output_data_plt_i386::do_write): Use the PIC PLT if output_is_position_independent. * testsuite/Makefile.am (check_PROGRAMS): Add basic_pie_test and two_file_pie_test. (basic_pie_test.o, basic_pie_test): New targets. (two_file_test_1_pie.o, two_file_test_1b_pie.o): New targets. (two_file_test_2_pie.o, two_file_test_main_pie.o): New targets. (two_file_pie_test): New target. * testsuite/Makefile.in: Rebuild. * README: Remove note saying that -pie is not supported.
