I don't quite understand what this change does, could you elaborate?
Without -jN (in backwards compatibility mode), the "cd" is a no-op
(whether it's terminated by `;' or not) because make will execute a
single shell per command, with cwd set to ${.OBJDIR}.
With -jN, "cd" becomes necessary because all commands are executed as
a script by one shell (the reason it was added in the first place),
but adding `;' is a no-op because commands are on separate lines.
