    Re: Have the linker report an error if the same script is used twice

    git commit 6ec6968b1b2 results in
    ... error: linker script file '/usr/local/lib64/libgcc_s.so' appears
multiple times
    collect2: error: ld returned 1 exit status
    FAIL: bootstrap

    This patch changes things so that an error is given only when a -T
    script or the default script is invoked more than once.  I'm still a
    little nervous that we match script file names, not the entire path.

        PR 24576
        * ldfile.c (enum script_open_style): New.
        (struct script_name_list): New.
        (ldfile_open_command_file_1): Take a script_open_style param
        rather than booleans.  Adjust callers.  Only fail when -T or
        default -T script is invoked twice.
        (ldfile_try_open_bfd): Revert last change.
