  13        However it is being assigned to a symbol declared within
  14        a section.  Therefore the symbol is section-relative and
  15        its value will include the offset of that section from
  16        the start of memory.  ie the declaration:
  17           text_start = ORIGIN (TEXTMEM);
  18        here will result in text_start having a value of 0x200.
  19        Hence we need to subtract the absolute value of the
  20        location counter at this point in order to give text_start
  21        a value that is truely absolute, and which coincidentally
  22        will allow the tests in script.exp to work.  */
