It always does.

No it doesn't.

I don't see how the fact that the script copies several large files
tells you anything about when the cd runs.


Remember that the working directory is a function of your current shell,
AND that every command make invokes is run in its own shell.  So a
command like:

        cd $(OBJ_DIR)

is a complete no-op, since as soon as this command is done the shell
will exit and there goes your working directory context.
