Adding binutils as a DEPS to allow DebugFission on Ubuntu Precise when compiling with clang.

DEPS

 # This file is automatically processed to create .DEPS.git which is the file
 # that gclient uses under git.
 #
 # See http://code.google.com/p/chromium/wiki/UsingGit
 #
 # To test manually, run:
 #   python tools/deps2git/deps2git.py -o .DEPS.git
 #   gclient runhooks
 # DO NOT CHECK IN CHANGES TO .DEPS.git. It will be automatically updated by
 # a bot when you modify this one.

You may want to get the binutils files checked in first, otherwise this looks ok
assuming the files for download are ready.
