Somebody of the mbx8xx authors found it useful to strip the bootables:

>From mbx8xx.cfg:

define make-exe
        $(LINK.c) $(AM_CFLAGS) $(AM_LDFLAGS) $(MBX8xx_LDFLAGS) \
            -o $(basename $@)_sym.exe $(LINK_OBJS) $(LINK_LIBS)
        $(NM) -g -n $(basename $@)_sym.exe > $(basename $@).nm
        cp $(basename $@)_sym.exe $(basename $@).exe
        $(STRIP) $(basename $@).exe
        $(SIZE) $(basename $@)_sym.exe

Note the $(STRIP).

I guess, simply removing the line containing the STRIP will produce the
result you want to see.
