* coffgen.c (coff_write_symbols): Check to see if a symbol's flags

       do not match it class and if necessary update the class.
       (null_error_handler): New function.  Suppresses the generation of
       bfd error messages.
     * coff64-rs6000.c (bfd_xcoff_backend_data): Update comment.
     * config/tc-tic4x.c (tic4x_globl): Call S_SET_EXTERNAL as well as
     S_SET_STORAGE_CLASS.
