Wouldn't it be better for .note.gnu.property to follow existing
practice?  It seems like everyone assumes word alignment for notes.
Also note that Elf64_Nhdr consists of odd number of words, which makes
the note data unaligned for xwords, causing the next note to be
unaligned relative to the segment alignment.
