Great! This is feasible for the 3.3 time frame.

I'm expecting that, once the self-host check-all is fixed, we won't have
problems here. The few check-all problems (about 3) seem to be regarding
configuration, not real bugs in the compiler, so I'm not expecting any
problem in the self-hosting test-suite.

But it'll take a while to create the bots. There were some, er, issues with
the Arndale (http://www.spinics.net/lists/kvm-arm/msg03723.html) and the
Chromebooks are not the best rack machines... ;)

Anyway, my aim is to get those 4 bots up and green by the 3.3 release.

Actually, this is a good idea, I'll set up a Beagle as a buildbot and see
what happens to it.

I agree. LLVM does a pretty good job at compiling for other ARM
architectures, but corner cases can be quite bad, and it's usually on them
that people will compare LLVM to GCC. A warning that we're primarily
focusing on v7 for the time being would be in order.
