 I think the problem isn't that the application isn't being built with
 -fPIC, but that libgcov.a hasn't been built with it.  Running a 'make'
 in /usr/src/gnu/lib/libgcov shows libgcov.c being built without that
 flag, despite the following being present in the Makefile:
 
 $(OBJS_T}: libgcov.c
 	${CC} -c ${CFLAGS} -DL${.PREFIX} -o ${.TARGET} ${.ALLSRC:M*.c}
 
 .if !defined(NO_PIC)
 ${OBJS_S}: libgcov.c
 	${CC} -c ${PICFLAG} ${CFLAGS} -DL${.PREFIX} -o ${.TARGET}
 ${.ALLSRC:M*.c}
 .endif
