Many thanks Ken. I've managed to get 1.17 to build outside of the
debian/ubuntu package building wrappers now, now I just need to work out
what the difference is in the packaging system.

BTW to get your configure line to work I had to disable multilib
otherwise I got ...

Ubuntu's package doesn't seem to build the multilib version anyway.
