Which is nice, but I'm trying to get the number of separate packages in
the base system down. I originally planned to replace bash with one of
the busybox shells (then Bruce happened), now I plan to do toysh but
have a bunch of commands like "mount" to implement first...
So I'm looking at this as "fun, but stopgap". That said, I've
downloaded the original public domain version and might loot cleaned up
versions of some of its code for toysh in toybox...

I need to find some time to update it. :)

armv4eb isn't fully supported because qemu still hasn't quite got
support for it (or so the qemu mailing list keeps saying), so I haven't
really tested it.
Last I checked armv6 was working, though.
Oh, sh4 needs a patched qemu. (The following patch whitespace-damaged
by cut and paste.)
