As a temporary *workaround* in order to link the driver (for those of us willing to use a "blob-ful" driver -- until a better solution is found) under 6.15 and beyond, the driver may be linked by editing /usr/src/broadcom-sta-6.30.223.271/Makefile to disable objtool during the final processing of wl.o. It's an ugly hack but it seems to work for me.
