    NB: --config-file is troublesome, because get_defaults_options() doesn't
    know about it, but we pretend --config-file is like --defaults-file.  In
    fact they behave differently: see the comments at the top of
    mysys/default.c for how --defaults-file should behave.

    This --config-file option behaves as:
    - If it has a directory name part (absolute or relative), then only this
      file is read; no error is given if the file doesn't exist
    - If the file has no directory name part, the standard locations are
      searched for a file of this name (and standard filename extensions are
      added if the file has no extension)
