Yes, this is an unsatisfactory solution as far as the current Hurd
maintainers' philosophy is concerned.  A proper solution, however,
will not effect busybox when running under Linux or BSD; any extra
code can be stripped away by the preprocessor using something along
the lines of:

  #ifdef PATH_MAX
    /* (Current) static solution.  */
  #else
    /* Dynamic solution using pathconf ().  */
  #endif /* PATH_MAX */
