binutils221: Fix missing section start/end label generation

* The code to generate section __start_set and __end_set symbols
  was using exp_provide() instead of exp_assign(), and exp_provide()
  appears to silently discard the symbol due to being assigned to '.'
  (the origin).

  This resulted in the symbols not being generated in the output file.

* Change to using exp_assign() and pray.
