Re: ld bug in the location counter calculation?

No - the documentation itself is incorrect.  The sentence that says:

  "Specifying @var{address} for a section will change the
   value of the location counter."

Should actually read:

  "Specifying @var{address} for a section will change the
   value of the location counter, provided that the section
   is non-empty.  (Empty sections are ignored)."

I will be checking in a patch to update the documentation.

  Put the address before the start of the .data section.  Ie change 
your linker script to be like this:

  /* append .data; it will be copied by crt0 to final __DATA_START__ */
  . = ALIGN(4);
  __INIT_DATA_START__ = .;

  . = __DATA_START__ ;

  .data : AT ( __INIT_DATA_START__ )
  {
    *(.data)
