Proposed patch

Hi Paul, Hi Jon,

  Would either of you like to try out this potential patch ?

  It adds local symbols to the linker map at the appropriate places, with a
  prefix of "(local) " so that they can be quickly identified.  (Note local
  symbols are displayed after global symbols for a given section, rather than
  being mixed in with the global symbols).

  It is not complete yet.  I think that I am going to have to add a command
  line option to control its use, as I expect that there are people out there
  who rely on the current format not changing.  Plus I will need to add a
  testcase or two to the testsuite.

  I did find that *some* local symbols are already included in the linker map,
  eg _GLOBAL_OFFSET_TABLE_ and at the moment such symbols will appear twice.
  So I ought to try to find a way to stop that from happening as well.

Cheers
  Nick
