Damaged dependency files

This isn't caused by GCC, or not directly anyway.  Firebird's
make.rules has:

	$(OBJ)/%.o: $(SRC_ROOT)/%.c
	$(CC) $(WCFLAGS) -c $(firstword $<) -o $@
	@sed -i -e "1s/:/: \$$(wildcard/" -e "\$$s/\(.*\)/\\1)/" $(patsubst
%.o,%.d,$@)

Something in that sed command does not work as expected; you should
look at the .d file before it is changed to see what's up (you can give
the -i flag an argument which it will use to make a backup of the original
file before it edits it; e.g.  -i.orig  will make a bla.d.orig).
