Here's a proposed patch for that.  I've confirmed we get identical
filesets from all three build methods with this.

Although this seems like clearly a bug, I'm not sure anyone would
thank us for changing the behavior in back branches; particularly
not packagers, who tend to pay close attention to the set of files
installed.  So I'm inclined to apply this to master only.
