    Scope libstdc++ configuration for vxworks to all versions
    
    When libstdc++ is enabled, the current high level configuration
    bits should apply the same to all versions of VxWorks.  Adjust the
    config triplets matching rules accordingly.

            * crossconfig.m4: Turn vxworks matcher into vxworks*.
            * configure.host: Likewise.
            * configure: Regenerate.
