Crunched objects (*.cro) are not usual executables.  You can reuse *.o files.

From bsd.prog.mk rules:

        cat/cat.ro: ${OBJS}
                ${CC} ${LDFLAGS} -nostdlib -r -Wl,-dc -o ${.TARGET} ${OBJS}

And generated Makefile (e.g. ${OBJDIR}/rescue/rescue.mk):

        cat.cro: cat/cat.ro
                ${NM} -ng cat/cat.ro | \
                ${AWK} '/^ *U / { next }; /^[0-9a-fA-F]+ C/ { next }; / main$$/ 
{ print "main _crunched_cat_stub"; next }; { print $$3 " " $$3 
"$$$$from$$$$cat" }' > cat.cro.syms
                ${OBJCOPY} --redefine-syms cat.cro.syms cat/cat.ro cat.cro

You'll probably want to audit all the common symbols involved too.
