test_shell does not seem to be valid make target in stock 1.0.9, there's
'unit'.  Trackdown suggests that the test_shell target was added around
Oct 3 and seems to have about 199 patch dependencies, so that's not an
easy option to apply to stock 1.0.9 to rule things out.  I put in a
test_unit instead and its results can be seen here

    curl http://koji.fedoraproject.org/koji/getfile?taskID=268980&name=build.log

If anyone has a patch to 1.0.9 to apply the test_shell target and the
associated tests without affecting the 1.0.9 code I'll be happy to give
it a try.  My darcs skills aren't up to correctly cherry picking the
required changesets.

I don't have direct access to a PPC machine right now to investigate
this directly, I can just submit the build requests to the fedora build
