Reading my comment ... it sounds a bit odd/misleading. It should have said:
 "I'm leaning that we don't want to cleanup the file. Not 100% sure so
I'm open to suggestions."

And yes. If we clean the file (with any target) then there'll be no
way to regenerate it when building from tarball. And thus we won't be
able to build Vulkan.
