Update SCons to latest checkpoint release, 1.2.0.d20090113....

third_party/scons/scons-local/SCons/Variables/ListVariable.py

 """engine.SCons.Variables.ListVariable
 
 This file defines the option type for SCons implementing 'lists'.
 
 A 'list' option may either be 'all', 'none' or a list of names
 separated by comma. After the option has been processed, the option
 value holds either the named list elements, all list elemens or no
 list elements at all.
 
 Usage example:
 
   list_of_libs = Split('x11 gl qt ical')
 
   opts = Variables()
   opts.Add(ListVariable('shared',
                       'libraries to build as shared libraries',
                       'all',
                       elems = list_of_libs))
   ...
   for lib in list_of_libs:
      if lib in env['shared']:
          env.SharedObject(...)
      else:
          env.Object(...)
