Hi,
you need both. xwayland.so is the Weston plugin that will automatically
execute /usr/bin/Xwayland when the first X11 app attempts to connect.

As above, it cannot work without Xwayland.

PPC64, is this a little-endian or a big-endian architecture?

You seem to be doing it right here, it just doesn't work.
If you redirect weston's both stdout and stderr to a file, you might
catch more messages from Xwayland which would hopefully shed more light
to why it seems to crash.
I have to say that PPC64 + Nouveau is probably a very little tested
combination. If your system happens to be also big-endian, I would
actually be expecting it to fail somehow since I don't think any
developer has such a setup to care of and BE is known to be potentially
troubled.
Does Xorg work by any chance?
Thanks,
