Remove unused hard link targets in Makefile

We use $BINARY_NAME-$ARCH format in Calico builds and packaging
containers. The hard link targets in Makefile are not used and can be
removed. When building multiarchs, new links without $ARCH in the
binary name will overwrite existing ones which may cause unexpected
behaviors.
