Note the makefile is supposed to get the svn revision, but I can't get
svnrevision to be either compiled or taken from my already installed
package, plus I suppose since we actually make a git repo from the
source it wouldn't work anyway... FIXME
* this fixes the wrong recipe names introduced by myself in #d525fee
* adjust patch names to match corresponding recipes
* additionally: create 'additional-files' folders as hint to some
ports that do not have a proper recipe yet
