$this->bbcode_second_pass_quote('redbrain', 'I') take a build master system which is it self a ARM system and I take some build clients which are ARM or x86_64 systems. I install on all of them Arch Linux and prepare them with distcc and the crostool-NG toolchain (only x86) (downloaded or as a self-build) and install base-devel group packages everywhere.
What you are describing will allow you to build your own packages from their respective PKGBUILD+files (if any) should you want to.
$this->bbcode_second_pass_quote('redbrain', 'T')hen I need a bunch of PKGBUILD files which are need for a base system (first I'll take all of the core dir right?) and compile all of them with makepkg. Then I get a lot of tar.gz files. Do I get a RootFS image here automatically here or is there an extra step to create that image?
Your rootfs is already on your devices from step 1. What do you want to accomplish? Do you want to compile everything yourself from source like gentoo? Arch ARM is a binary distro/you do not need to do this.
