We're using full system emulation with upstream qemu.  It's
surprisingly simple to set up, it supports multiple virtual CPUs up to
‘-smp 8’, and provided you have a fast enough host hardware isn't too
bad for development.  Of course compiling GCC with bootstrapping is
still going to take a long time.  For instructions see the readme
