I've already got ppc32 support working.  Adding a new arch is just a matter of 
adding a kernel config and uClibc config to configs/

I spent a couple days researching what to do here and ended up settling on:

1) build binutils for desired target

2) build GCC using (1) as a cross compiler.  This is a limited form of GCC (no 
thread support) targeted as uClibc

3) build kernel using (2) and installer headers into our new sysroot

4) build uClibc using (2) and (3)

5) build busybox using (2) and (4)

The whole process takes about 30 minutes on my laptop using -j1 which isn't all 
that bad.  It's certainly faster than doing a distro install with TCG :-)

qemu-jeos.git contains git submodules for binutils, GCC, linux, uClibc, and 
busybox plus miscellaneous scripts needed to make a working initramfs.

Once we get more ARCHs working, I'll add a cronjob to qemu.org to build weekly 
binary packages so that for most people, all you have to do is grab an RPM/DEB 
with prebuilt binaries.
