I am fixing packages whose method is inferred.

Sorry. My message after the commit log was misleading.
Rethinking now, a better message would be:
"Currently there is no package in the tree that uses inferred site method, and
that is why the autobuilder didn't caught this. We had packages using inferred
site method in the past, the last one was 'expect', but since they didn't have a
hash file (for a license or extra-download for example) the build didn't error

There is no example in the tree right now, but they can either live in a
br2-external somewhere or they can be added to the tree in the future.
I don't have a real package with this problem.

I stumbled on this because I am creating automated tests for the download infra.
They setup a SCM remote in the docker image by calling git daemon, svnserver,
... depending on the download method and download a package. Here is one package
under test [1], the test failing before this patch [2] and the test passing
after this patch [3].

Correct. The last one was 'expect', it now uses a tarball instead of cvs.

You can reproduce the problem I a trying to fix by doing this:
$ git revert 23ab6cb162b7456925e2c3df4917cf9b45868d55
$ touch package/expect/expect.hash
$ make expect-source
ERROR: No hash found for expect-2014-05-02.tar.gz
