Details:

When cross-building default-octave:

In log/of-optim:

:
error-helpers.cc:60:8: error: 'cerr' is not a member of 'std'
   std::cerr << msg;
        ^~~~
error-helpers.cc:60:8: note: suggested alternative: 'errc'
   std::cerr << msg;
        ^~~~
        errc
Makefile:64: recipe for target 'error-helpers.o' failed
make[2]: *** [error-helpers.o] Error 1


Adding

#include <iostream>

in error-helper.cc makes the build go on. But I don't know if this is a proper
fix.
