[Buildroot] Why there are two colons on .stamp_built rule?

Hello,

I was looking for something in pkg-generic.mk and then I noticed that
the rule for .stamp_built has two colons.

This is the line:
  $(BUILD_DIR)/%/.stamp_built::

Is it on purpose or it's just a simple harmless mistake? Do the two
colons even mean something?

Best regards,
Asaf.
