Commit: Create a single linker script for DWARF sections

[Nick Clifton <nickc at redhat dot com>]

Hi Guys,

  I am working on a patch which will add some extensions to the DWARF
  sections in linker scripts[1].  We have a lot of scripts that include
  DWARF sections and having to modify them all each time I want to add a
  new section seemed like a waste of time.  So instead I created the
  patch below which creates a single DWARF.sc script fragment which is
  then included into any script that uses DWARF sections.

  Tested, without any regressions, on a wide variety of different
  toolchains.

Cheers
  Nick

[1] I am working on extending linker garbage collection so that when a
text section is removed any debug information associated with that
section is also removed.  Currently I have a local patch that makes GAS
produce .debug_line.text.<foo> sections and these need to be merged into
the proper .debug_line section when a final link occurs.
