[Bug c/61899] gcc/Makefile.in: compile failure occasionally while parallel make enabled

--- Comment #1 from hongxu jia <hongxu.jia at windriver dot com> ---
Here is my solution:

gcc/Makefile.in: add missing errors.o/gcc-ar.o/gcc-nm.o/gcc-ranlib.o to OBJS

While parallel make, the '$(ALL_HOST_OBJS) : | $(generated_files)' rule
doesn't work for these missing objects. And there was potential compile
failure.
