[PKGBUILD] bin32-lha 1.17

Hi guys.

This is my first PKGBUILD, which is mostly just a slightly edit of the original one. Still, since this my very first PKGBUILD, I would like to hear the opinions of your guys to make sure I didn't screw up something.

The reason for this PKGBUILD is that the lha package in x86_64 extra repository is currently not functional, because it is in fact a 32 bit binary. Since the developer does not provide source, nor binary for 64 bit, our only option to get the package working on 64 bit Arch is to either roll back to the older version, or install the necessary 32 bit library to get the current version working (which is what this PKGBUILD aim to do).

And that's it! Thanks for your time guys.
