My approach won't work on whatever you consider "latest Ubuntu".
It only works up to glibc 2.22 and Xenial already comes with 2.23.
If someone has a working solution I'd be interested too, because then also Debian Stretch would become an option again.

@klausade:
Indeed you're right. Sorry for the inconvenience! I neglected to document these steps because dpkg-source didn't record them.
Nice to see, someone is actually checking what I've been doing!
I'll update the instructions.
