Hadrian bindist duplicates bin/ executables

Summary

When building and installing ghc-9.4.1 with hadrian binary-dist-dir duplicate bin/ files are installed (eg ghc and ghc-9.4.1, etc)

Steps to reproduce

Hadrian install of ghc-9.4.1 using bindist, I end up with:

Expected behavior

For 9.2.4 the directory looks like that:

(I have a vague recollection I might even have been involved in this.)

It might just be a change missing in the 9.4 branch, possibly?
