New Revision: 257658
URL: http://svnweb.freebsd.org/changeset/base/257658

Log:
  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.
