package: add a <pkg>_EXTRA_DOWNLOADS variable
Converting the external toolchain logic into a package raises a very special use case that wasn't handled by the package infrastructure: the Blackfin toolchain is delivered as two tarballs instead of one. Unfortunately <pkg>_SOURCE only allows to pass one tarball name. However, we really want both tarballs to be known by the package infrastructure, so that the normal 'source' and 'external-deps' mechanism work fine. In order to achieve this, we add a <pkg>_EXTRA_DOWNLOADS variable, which allows a package to list other stuff it would like to see downloaded, but that are otherwise not used by the package infrastructure itself: it is up to the package to do it by itself.
