The above is almost correct.

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

(Adding propagated is sufficient to cause it to be passed
to dependencies.  I generally recommend making the feature
optional, so that it only appears when it's used)
