New Revision: 301286
URL: https://svnweb.freebsd.org/changeset/base/301286

Log:
  WITH_CCACHE_BUILD + WITH_META_MODE: Ignore ccache changes.
  
  Ccache will not affect the output of the objects, so just ignore it for
  meta mode handling.  This avoids having everything rebuild if ccache is
  updated.
