--- Comment #8 from H.J. Lu <hjl.tools at gmail dot com> ---
I am adding:

/* Align an address upward to a boundary, expressed as a number of bytes.
   E.g. align to an 8-byte boundary with argument of 8.  */
#define ELF_ALIGN_UP(addr, boundary) \
  (((bfd_vma) (addr) + ((boundary) - 1)) & ~ (bfd_vma) ((boundary) -1))

/* Compute the offset of the note descriptor from size of note entry's
   owner string and note alignment.  */
#define ELF_NOTE_DESC_OFFSET(namesz, align) \
  ELF_ALIGN_UP (offsetof (Elf_External_Note, name) + (namesz), (align))

/* Compute the offset of the next note entry from size of note entry's
   owner string, size of the note descriptor and note alignment.  */
#define ELF_NOTE_NEXT_OFFSET(namesz, descsz, align) \
  ELF_ALIGN_UP (ELF_NOTE_DESC_OFFSET ((namesz), (align)) + (descsz), \
                (align))

to binutils.  I will also add something similar to glibc.
