I shall allow you to fix the homepage link, as I don't use a debian-based distro and haven't got a clue how to do so.

I could undoubtedly figure it out easily enough, but frankly why bother when you can do so instead, it isn't like I will be using the information a lot...
That would also explain why I was confused by the "lack" of an x86 package.

In ArchLinux, the
PKGBUILD file does all the work, and includes an "arch" array of supported architectures. Whatever instructions (like
this) are given, that is what the ArchLinux auto-builds make.
It isn't very fancy, I'm afraid.
