tests: work around getopt portability issues

Browse Source 
On some systems, we don't use our getopt.  As a consequence the error
messages vary:

    $ bison --skeleton
    bison: option requires an argument -- skeleton
    Try 'bison --help' for more information.

instead of

    bison: option '--skeleton' requires an argument
    Try 'bison --help' for more information.

Reported by Jannick and Nelson H. F. Beebe.
