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.
This library will allow us to port more multimedia programs and games,
since it's a common dependency of such projects. I was looking at
Scummvm's dependencies in particular, with a goal of porting them all
eventually, so that we can have Myst running in Serenity!
