The OPT string is a free-form string, the contents of which are not
specified in JEP 223.
If a user-specified opt string is not specified, the build system makes
up a default opt string. This uses some heuristics to form a
more-or-less unique string, based on the current time, user name and
base directory name. However, you should not rely on the opt string to
really *mean* something. If you want to pass a date string with a
specific format for use in your internal processes, please use the
--with-version-opt argument to configure.
