I didn't worry about this any more after I found that the problem went 
away if I changed my application link-edit command as follows (from 
RTEMS/make/custrom/uC5282.cfg):
 define make-exe
-       $(LINK.c) $(AM_CFLAGS) -m5200 $(AM_LDFLAGS) -qnolinkcmds -o 
$(basename $@).nxe \
-           $(LINK_OBJS) $(LINK_LIBS) -Wl,-Tlinkcmds
+       $(LINK.c) $(AM_CFLAGS) $(AM_LDFLAGS) -o $(basename $@).nxe \
+           $(LINK_OBJS) $(LINK_LIBS)
        $(OBJCOPY) -O binary --strip-all $(basename $@).nxe $@
        $(SIZE) $(basename $@).nxe
 endef
