This makes it easier for distros to use the Makefile when creating
packages. It enables us to specify a base destination directory to
install the project files to. E.g., on Solus, when creating eopkgs, files
must be installed to a special directory path, which becomes the package
files. I believe Fedora packages, and others, are the same.
