This is the same issue as my question two weeks ago.


It seems that gcc-3.4 is at fault here, since all recent
2.1.x and 2.9.x versions give the same errors.

When not stripped, the octave binary gives
   # make install

   ... [ many more ] ...
   warning: kpathsea: variable `O' references itself (eventually)
   ... [ many more ] ...
   Aborted (core dumped)
