Broken libxmp packages

[knight-ryu12]

seems like #104 pkgbuild ships with wrongly linked thing, therefore it ships broken packages. :cry: The things, (That I am not quite sure+ speculation), is ./configure is not being good to detect on it.

Can also confirm I get this issue:

random people turning up to confirm issues aren't helpful. They just create unnecessary noise in the issue tracker.

The problem is that libxmp, like many other open source packages, is written as though windows and unix compatible systems are the only systems that exist. I've added a patch to disable the use of external helpers when the popen tests fail which should hopefully help. https://github.com/devkitPro/pacman-packages/commit/e545cdbe7621eeb4dfda363da425c824f38957da

I suppose I should have realised that you hadn't tested the package you PR'd when I had to fix it before packaging - https://github.com/devkitPro/pacman-packages/commit/9dac92f6215884ae358cb757ab601d1746c41fd6
