Key to Flags:
  W (write), A (alloc), X (execute), M (merge), S (strings), I (info),
  L (link order), O (extra OS processing required), G (group), T (TLS),
  C (compressed), x (unknown), o (OS specific), E (exclude),
  p (processor specific)
address@hidden gas]$ 

obj_elf_version pads note section to 4 byte alignment:

frag_align (2, 0, 0);

But it doesn't set section alignment to 4 bytes.
