Identify t/*/*.t test failing because of file permissions

tim> I've added

That doesn't help for the patch. The perl5.004m4t1.patch.gz contained

    touch t/lib/dosglob.t

but no

    chmod +x t/lib/dosglob.t

Short term I'd recommend Ilya's one-line patch to t/TEST because it at
least saves us debugging time. Stupid me lost over an hour not
understanding the reason for the failure. Here it is:
