Log:
  MFC r257658 (modified to apply to stable/8):
  
  For C++ programs, don't emit any explicit dependency to libstdc++.a or
  libc++.a during the early build stages (bootstrap-tools, build-tools,
  cross-tools), since it is not possible to know in advance which C++
  library is available on the host system.
  
  Instead, just use the bootstrap compiler's built-in default.  This
  should eventually make it possible to build stable/9 on head, or on
  stable/10, which ship without libstdc++ by default.
  
  [Note: this should get the stable/8 tinderbox at least a bit further in
  buildworld.]
