    [gdb/tdep] Declare score-*-* target obsolete
    
    I tried out the script gdb/gdb_mbuild.sh, and ran into:
    ...
    score-elf ...
    ... configure --target=score-elf
    ... make score-elf
    ... run score-elf
    score-elf: gdb dumped core
    Terminated
    ...
    
    Gdb runs into this internal error in initialize_current_architecture:
    ...
      if (! gdbarch_update_p (info))
        internal_error (__FILE__, __LINE__,
                        _("initialize_current_architecture: Selection of "
                          "initial architecture failed"));
    ...
    
    The call to gdbarch_update_p fails because commit 575b4c298a6 ("gdb: Remove
    support for S+core") removed support for the architecture.
    
    Fix this by adding score-*-* to the list of obsolete targets in
    gdb/configure.tgt, such that we're no longer able to build the configuration:
    ...
    *** Configuration score-unknown-elf is obsolete.
    *** Support has been REMOVED.
    make: *** [Makefile:12806: configure-gdb] Error 1
    ...
    
    Also remove the related line from the "Target Instruction Set Architectures"
    list in gdb/MAINTAINERS, such that gdb/gdb_mbuild.sh no longer tries to build
    it.
