Bo,

If that's urgent for you I can suggest a workaround, but there might be a better 
solution.
Here it goes:

import feature ;
feature.feature fpic : off on : propagated optional composite ;
feature.compose <fpic>on : <cxxflags>-fPIC ;

     <library>../../../external/boost/libs/chrono/build//<link>static/<fpic>on
     
<library>../../../external/boost/libs/serialization/build//<link>static/<fpic>on
