Hi Joost,

I tried that for the Beaglebone Black I also use.
It will not work constantly enough well to setup
a complete system. There are two sources for trouble:
The makefiles access "meta-applications" like moc fpr qt
and either try to start a arm binary on my AMD64 PC or
they use moc of the AMD64 arch. and produce some rubbish
from the point of view of the ARM arch.
(ok, moc is bad example, since it is platform idenpendant
regarding ist outout I think, but...)
Or: The software isn't written that clean and import
low level headers (kernel...) of the AMD64 platform
into the ARM compilation results.
I also tried distcc and it does not work for me. 
May be its me or distcc. The results were..."mixed"...
Since that I compile all the stuff (accept the kernel
itsself because it is "self contained") on the target
itsself. With the beaglebone black this only a matter of
waiting (not THAT long: 1GHz CPU single core with 512MB RAM
and an mobile hd).
With that tiny Arietta and await waiting for days until
I have a system of my choice.
But that is ok, since the main purpose of this tiny Linux
thingy is only the steering of some electronics. Nothing fancy...
So I need only a few addtional applications.

But the beaglebone black is acapble enough to run SIMH
emulating a PDP11 with an ancient UNIX (with an original
login of Dennis Ritchie ;) at 100% "original speed".
Or an ATARi800 emulator (also at 100% original speed).
Or other nice things... :)

Best regards,
Meino
