OK, had time to take a look at it. Please correct me if I'm wrong:
You are creating gcc links to distcc in a temp dir, so that distcc can be 
called by usual command "gcc":
  cd /tmp/DISTCC
  ln -vfs /usr/bin/distcc gcc
  ln -vfs /usr/bin/distcc cc
  ln -vfs /usr/bin/distcc g++
  ln -vfs /usr/bin/distcc c++
  ln -vfs /usr/bin/distcc arm-slackware-linux-${EABI}c++
  ln -vfs /usr/bin/distcc arm-slackware-linux-${EABI}g++
  ln -vfs /usr/bin/distcc arm-slackware-linux-${EABI}gcc

After and to make sure distcc is called instead of original gcc you place the 
directory with distcc symlinks at the beginning of the PATH. So it's not 
needed to specify CC in Makefiles:
  PATH=/tmp/DISTCC:$PATH 

Before distcc can be called it needs info what hosts to contact and the number 
of jobs the host should run:
  export DISTCC_HOSTS="hostnameA/3 hostnameB/1 hostnameC/1"

And I probably have to do the same trick with the PATH on the host machines so 
that the cross compiler is run?
