Not AFAIK, they remain Debian Wheezy based.

Plus I believe we check in the flex/bison output, so it shouldn't be
being changed except explicitly.

Now. That said... This is an armhf build which happens on a single
machine which is not regularly reinstalled and is available to people
other than osstest, but looking at lastlog nobody has been using it
recently (we have better personal option these days). So the machine
should still be pristine Wheezy etc.

A second thing of interest is that the log shows that despite things
being checked in flex has been run:
        /usr/bin/flex --header-file=libxlu_disk_l.h --outfile=libxlu_disk_l.c 
Perhaps a git timestamping issue, given that tools/libxl in this branch
hasn't changed since May.

Looking at the latest 4.4 run flex wasn't rerun there, two minutes after
this one.

Lastly, even having rerun flex -- it still shouldn't fail!

I'm just running a dist-tools of staging-4.3 on this very system -- I'll
let you know what happens/...
