    [libstdc++-v3] [rtems] enable filesystem support
    
    mkdir, chdir and chmod functions are defined in librtemscpu, that
    doesn't get linked in during libstdc++-v3 configure, but applications
    use -qrtems for linking, which brings those symbols in, so it makes
    sense to mark them as available so that the C++ filesystem APIs are
    enabled.
    
    
    for  libstdc++-v3/ChangeLog
    
            * configure.ac [*-*-rtems*]: Set chdir, chmod and mkdir as
            available.
            * configure: Rebuilt.
