    gold: Properly align the NT_GNU_PROPERTY_TYPE_0 note

    The NT_GNU_PROPERTY_TYPE_0 note should be aligned to 8 bytes for 64-bit
    ELF as specified by gABI.  A note section can be only placed in a PT_NOTE
    segment with the same alignment.

            * layout.cc (Layout::attach_allocated_section_to_segment): Place
            a note section in a PT_NOTE segment with the same alignment.  Set
            the alignment of the PT_NOTE segment from the alignment of the
            note section.
            (Layout::create_note): Align the NT_GNU_PROPERTY_TYPE_0 note to 8
            bytes for 64-bit ELF.
            (Layout::segment_precedes): Place segments with larger alignments
            first.
            * output.cc (Output_segment::Output_segment): Initialize align_.
            * output.h (Output_segment): Add align, set_align and align_.
            * testsuite/Makefile.am (gnu_property_test.stdout): Pass -lhSWn
            to $(TEST_READELF).
            (gnu_property_test): Pass --build-id to ld.
            * testsuite/Makefile.in: Regenerated.
            * testsuite/gnu_property_test.sh (check_alignment): New.
            Use check_alignment to check the NT_GNU_PROPERTY_TYPE_0 note
            alignment.  Verify that there are 2 PT_NOTE segments.
