It's essentially impossible to talk about variables by themselves: the
only way it makes sense to talk about them is by showing how they are
used.  If you show me a complete example makefile that uses those two
different forms, I can tell you what it will do and how make will treat
them.

Of course, if you do that you can just run make yourself and see what
happens without needing to ask :).

However, the short answer is no, they are not even close to being
equivalent.
