The darwin toolset does not allow to specify static or shared linking
for searched libraries. Looking at darwin.jam:'actions link' I see
"$(CONFIG_COMMAND)" ... -l$(FINDLIBS-SA) -l$(FINDLIBS-ST)
whilst gcc.jam has:
$(START-GROUP) $(FINDLIBS-ST-PFX) -l$(FINDLIBS-ST) $(FINDLIBS-SA-PFX) -l$(FINDLIBS-SA) CRegister $(END-GROUP)
with those extra variables set in gcc.jam:init-link-flags. I imagine that if you adjust darwin.jam 'link'
action, and also modify init-link-flags to set variables similar to 'gnu' linker type, things
might work, but I don't have OSX machine to verify such a change myself.
