they aren't necessarily (builddir != srcdir) but I don't think we need to
cater for that case. The results are in git, this script is only there to to
be able to quickly reproduce them when we change things so there's no need
to be able to build this from a tarball. I've fixed it now, though I figured
I'd use dirname instead of basename, just to be different ;)
