Extended version of Jon's patch

Hi Jon,

  Your patch is good, but it misses a couple of points:

  * A change similar to the one in coffgen.c is needed in elf.c for ELF based
targets.

  * The assembler needs to be updated as well so that it's
--compress-debug-sections option only compresses when it is effective.

   * The documentation needs to be updated to explicitly mention that
compression only happens when it is worthwhile.


I have uploaded an extended version of your patch which should handle these
points.  Please could you try it out and let me know if it works for you.

Cheers
  Nick
