The temporary fix was to add an -N flag to enable networking during build() and package(). https://projects.parabolagnulinux.org/packages/libretools.git/commit/?id=724cc90d771d840c4579e3b2443cad21fd6fe231

I've implemented 'distcc-tool', which can be used to tunnel distcc out. I haven't integrated it with libremakepkg yet.

It is used like this:

host# distcc-tool odaemon /path/to/chroot &
chroot$ distcc-tool idaemon "$DISTCC_HOSTS" &
chroot$ DISTCC_HOSTS="$(distcc-tool rewrite "$DISTCC_HOSTS")" 

The only dependency that isn't in base-devel is 'socat'.

I added integration for distcc-tool
