    Fix internal error from command line with unbalanced --start-lib/--end-lib.

    The problem is that while the command line isn't trivially empty,
    it contains no input files. As gold tries to configure the number
    of threads to use based on the number of input files, this causes
    the assertion failure above. Fix this problem by making the logic
    in gold.cc more robust and also adding a better error message
    about --start-lib to options.cc.

        * gold.cc (queue_initial_tasks) Check for number of real input files.
        * options.cc (Command_line::process) Check for unterminated --start-lib
        options.
        * testsuite/Makefile.am: Add new test script.
        * testsuite/Makefile.in: Regenerate.
        * testsuite/check_empty_command_lines.sh: New test script.
