[Yhc] Linux PowerPC Buildbot slave set up

I decided to run the buildbot in a chroot (bind-mounting required
directories like /bin, /usr, and so on) to give my system (now Ubuntu
"Dapper Drake" on my old G3 powerpc) a bit of protection, and that seems
to be working.

Soon after getting the buildbot working, though, and with GHC plugging
away at Yhc's code, my machine decided to lock up. Gkrellm is great, I
can see green cpu usage for "nice" processes (such as I made the
buildbot slave), and I saw that I had about 200 megabytes of swap usage
at that point. Well I'm not giving up, just warning that my computer
seems a bit unreliable! :) (plus, can't wait till Yhc can compile itself
for doubled testing and lower resource usage (hmm, proper testing
shouldn't start with an old alpha version, but self-compilation and
using the self-compiled version to get the exact same results[1] should
be a good test in general) ... or could a standard way to use hugs be
set up perhaps, rather than necessarily doing the testing using the
resource-hungry ghc?)

transparent, particularly when date-of-compilation preprocessor symbols
are used.
