build fail on debian

[Thorsten Meyer]

I've just tried to build from the current tip (a262b41eaa15) on my debian
machine. It's been my first time after the introduction of the gnulib stuff. So
I have rerun autogen and configure. The make command succeeded. However, if I
try to do
        ./run-octave
afterwards I get the following:

address@hidden:$ ./run-octave
