Binding is designed so that components can react when data changes.
But you don't really care if extLinkURL changes. What you care about
is what its value is when the linkButton is clicked. So what you need
in the click attribute is just a normal function call with a normal
variable as the argument.
<mx:LinkButton label="{extLink}" click="loadXternalURL(extLinkURL)"
id="LinkBtn2" />
When the button is clicked loadXternalURL will be called and will be
passed the value of extLinkURL.
