Eek. That can't be right. The previous version did not modify any
global value of tool-bar-map, but made a local let-binding.
The changed version first creates a let-binding, _then_ makes a local
variable. What will happen when the let-binding is dissolved?

Making a variable buffer-local within a `let'-binding for that
variable does not work reliably, unless the buffer in which you do
this is not current either on entry to or exit from the `let'.
This is because `let' does not distinguish between different kinds
of bindings; it knows only which variable the binding was made for.
