Even if they do match, autolink expect boost libraries to be on the 
compiler library search path. With boost.build we don't need to change 
library search path, but we specify dependent targets with complete 
paths instead. So autolink code is already prettu useless if boost 
libraries are linked to projects build by BB.

Do I miss something?
