IHEX: Do not allow records to cross a 64K boundary

[Nick Clifton]

Hi Guys,

  I am applying the patch below, developed by Graham Stott, to fix a
  bug in the IHEX implementation.  The IHEX standard says that records
  should not cross a 64K boundary - instead they should wrap around to
  the start of the section.

Cheers
        Nick

        * ihex.c (ihex_write_object_contents): Do not allow records to
        cross a 64K boundary - wrap if necessary.
