This doesn't hurt compiling because we basically build all .o from top Makefile, before entering Makefile.target, but it will affact arriving per-object libs support. The starting point of $(obj) is passed in as argument of unnest-vars, as well as nested variables, so that different Makefiles can pass in a right value.
