When you ran it separately, did you say BINDIST=YES ? If you didn't then
it would have used the inplace package.conf.d, not the bindisttest one.

I recently added some "ghc-pkg check -v" calls in the validate script
incidentally, so if you log the output of the validate run then that
might give some more clues as to when/how it goes wrong.

test_bindist in bindisttest/ removes the entire
    "bindisttest/install   dir"
tree before installing the bindist there.
