While I agree with the patch you're proposing, I was wondering which
patch was introducing the regression. And I didn't find where the
regression could be coming from. Looking more closely at one of the
build results, you see that the tarballs are only extracted at the
make legal-info invocation, which doesn't make any sense: "make" is
executed before "make legal-info" in the autobuilders. So apparently,
nothing gets built at all during "make", and it's only at the "make
legal-info" step that packages are extracted.

So indeed your patch looks good, but it will not solve the autobuilders
problems I believe.
