Not in particular, other than our variable (ISI_TOP) is used in
referencing ${.CURDIR} and ${.OBJDIR}, and it's easy to make mistakes if
you goof up the dot-dots. With a properly defined directory like that it
makes things unambiguous in my mind and with a proper name it makes pathing
more intuitive than it currently is. Besides, it would make some other
things cleaner, like the dot-dot magic that config(8), etc does.
