On the powerful machine
-----------------------
Retrieve a prebuilt crosstool-ng toolchain such as https://archlinuxarm.org/builder/xtools/x-tools6h.tar.xz
so that the toolchain is available in /home/your_user/x-tools[6h|7h|8]/

Install distcc (yaourt -S distcc)

Then run:
> DISTCCD_PATH=/home/your_user/x-tools[6h|7h|8]/arm-unknown-linux-gnueabi[hf]/bin distccd --verbose --no-detach --allow <master-ip> --log-stderr --nice 0


On Raspberry pi
---------------

> sudo apt-get install distcc
> export PATH=/usr/lib/distcc:${PATH}

Edit ~/.distcc/hosts to resemble the following:

192.168.1.100 <-- ip of the powerful machine
--localslots=1
--randomize

Then 'configure' and 'make' the needed component ...
