ChangeLog os9kread.c stabsread.c remote-os9k.c symfile.c
	target.c

        * os9kread.c (fill_sym): check compiler verion number for pre-
        UltraC compiler.
        * os9kread.c (os9k_process_one_symbol): address of symbol is
        relative to section not module.
        * stabsread.c (define_symbol): add symbol type 's' as local
        symbol for os9k.
        * remote-os9k.c: add command 'set monitor_log' to turn on or off
        monitor logging.
        * remote-os9k.c: fix bug in delete breakpoint, single step trace.
        * remote-os9k.c: fix bug in 'set remotebaud' function.
        * remote-os9k.c (rombug_link): minimize checking so to improve
        speed.
        * symfile.c (symfile_command): check if failed to link, also make
        the command be able to accept more than one filenames.
        * target.c (target_link): check if failed to link with rombug.
