New Revision: 305145
URL: https://svnweb.freebsd.org/changeset/base/305145

Log:
  DIRDEPS_BUILD: Avoid cyclic dependency with libc++.
  
  The DIRDEPS_BUILD does not have a 'make includes' phase, so it would
  otherwise want libc++ to be fully built/staged before building
  libgcc.  Using the header directly works.
