For each library built two variants of pkg-config files are created from a per-library template: an "official" one for installation on the user's system, and one used for building internal tools, like e.g. qemu. Instead of the template which is looking very similar for all libraries generate the pkg-config files directly from make variables. This will reduce the need to specify some pkg-config file entries in the templates, as the contents can easily be generated from available data (e.g. "Version:" and "Requires.private:" entries). Especially the variant used for building internal tools needs to gain additional runtime link parameters for the internally used libraries, as otherwise those won't be found by the users (e.g. qemu).
