Right - for the mjpegtools programs (lav2wav for example). I didn't
mean to imply that external programs or other projects had been
fixed on the x86_64 architecture ;)
There were issues in mjpegtools that were fixed for x86_64 along with
a few general endian issues for big endian systems such as PPC. Those
were fixed. Didn't fix streamer because it's not in mjpegtools :)

mjpegtools' mp2enc is rejecting the file - but mjpegtools didn't
produce the file that I can see.

Where does 'streamer' come from? It's not part of mjpegtools. Does
"streamer" have a mailinglist or is this also the place for streamer
issues?

mjpegtools works, lav2wav and others give valid headers and data the
last I checked. If there are problems with lavrec, lav2wav, etc
they'll be fixed as soon as possible.
Who's in charge of 'streamer'? There's nothing in the mjpegtools
source tree that is called "streamer" ...
