[arch-general] Android support in Linux Arch

[Anatol Pomozov]

Hi,

As there is no strong consensus on what to do with Android development
tools then I am going to leave the situation as-is. Arch users will
keep either installing the packages using Android installer or by AUR
packages.

I am going to move packages android-tool and android-udev to
[community]. These are small packages that many people find useful.
