Thanks very much for pointing this out. I'll update the tarball
shortly. I must have broken the emulator port while working on the
Dream port.

Your compiler should be fine. I had to compile my own toolchain
because I use a Mac, and doing anything with GNU libc on a Mac is very
painful. :-)

You're right about the chip type. The goldfish machine description
(platform/goldfish/tools/machines.py) uses the arm926ejs chip, so as
long as your port does the same you should be fine. I just used pxa
because when I was doing the port (which was a while ago) the pxa
platform was a little more up-to-date and easier to read. None of the
actual code from the PXA port gets used anywhere else, so machines.py
should be the only important file.
Good luck!
