You always have option to rebuild everything for that particular toolkit. For 
a newly added compiler setting, bjam will rebuild everything.Otherwise a clean 
rebuild is only the solution.

Since bjam basically works with files i.e. it cannot decipher what changed in 
jamfile since last update, only a clean rebuild is the solution.

I would love this feature though, if there was any way to make it work 
partially. :)
