Provided I could use Runway 20, I wouldn't be particularly concerned!
A gusting TAF means that at some point in any ten minute period, the wind speed might exceed the mean by 10kt or more.
As long as the crosswind factor isn't beyond my capabilities (which I consider to be somewhat less than the published figure), shouldn't be too much of a hardship. Depending on the aircraft type, higher approach speed or lesser flap settings can all be used to make things more comfortable.
