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.
PR gold/22914
PR gold/23535
* 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.
