* script-sections.cc (Sections_element::allocate_to_segment): Add
	orphan parameter.
	(Output_section_definition::allocate_to_segment): Likewise.
	(Orphan_output_section::allocate_to_segment): Likewise.
	(Script_sections::attach_sections_using_phdrs_clause): Don't
	propagate non-PT_LOAD segments to orphan sections.
	* testsuite/Makefile.am (script_test_3.stdout): Generate using
	readelf rather than objdump.
	* testsuite/script_test_3.sh: Adjust accordingly.  Test that
	.interp section and PT_INTERP segment are the same size.
	* testsuite/Makefile.in: Rebuild.
