I was able to reproduce the issue. Modifying the 'gnulib-tool.py'
shell script in the 'gnulib' submodule so that -B is passed to
'python3' fixes it for me.

Leaving it without a ChangeLog entry for now just incase someone has a
better idea. I have no clue if this has a noticeable performance
impact or not.
