New Revision: 278223
URL: https://svnweb.freebsd.org/changeset/base/278223

Log:
  For now, add -stdlib=libc++ to the flags for building clang, since that
  makes it easier to build head on stable/9, where libstdc++ is still the
  default.  We can revisit this when somebody will try to build base with
  gcc 4.8.1 or higher, and its included libstdc++.
