This ensures the required binary files are installed to the correct
location and data files are copied to their default location so the
`--refdir` argument isn't needed when launching the game.
Some ports may have more than one `config.sub` that is in use (vendored
dependencies, etc.). Instead of fiddling about with space-delimited
strings, let's just make that setting into an array right away.
We currently have no valid use case for having a `port` property
different from the directory name the port's residing in. We do have
issues when this is the case when referencing dependencies, so let's
make sure all ports have a sensible `port` property to begin with.
All of these patches did the same thing, which is already in upstream
config.sub.
With this change, we need only add `use_fresh_config_sub=true` to
the package.sh file.
Note that this is not done automatically in case the port has a modified
config.sub file.
