Very nice, great work! It works as expected. I tested with both distcc
and icecc and both work well with DISTCC=y.

Also worth noting, is that distcc has a patch to work without DISTCC=y
in pump mode (though pump mode doesn't work super great with the kernel
as some of the include processing takes a long time). When I have some
free time, I may also try to patch icecc to work with it, as in my
experience, it performs better.

Regardless, I think your patch would be very valuable to be in upstream
so there's at least some way to use the existing versions of distcc and
icecc.

Thanks!
