    gdb-add-index always generates an error when libdebuginfod wasn't compiled in
    
    gdb-add-index runs gdb with -iex 'set debuginfod enabled off'.  If gdb
    is not compiled against libdebuginfod this causes an unnecessary error
    message to be printed to stderr indicating that gdb was not built with
    debuginfod support.
    
    Fix this by changing the 'set debuginfod enabled off' command to a
    no-op when gdb isn't built with libdebuginfod.
