Don't recommend an AUR helper for Arch

Do not recommend an AUR helper, as they go in and out of support all the time(not to mention that yaourt specifically is insecure and unsupported), rather link to the wiki page of AUR which contains manual build instructions.

Base Arch Linux install does not come with a compiler toolchain.

Also changed instances of "ArchLinux" into "Arch Linux".

Fixed typos.
