The asterisk means it is built by 'all'. But, I only see the following in this Makefile. # Default target all: zImage Seeing arch/sparc/boot/Makefile, it is true $(boot)/image is generated as a side-effect of zImage, but it it true for both 32-bit and 64-bit. I think it is even better to rewrite archhelp to unify the 32/64 bits. > echo '* zImage - stripped kernel image ($(boot)/zImage)'
