Follow-up Comment #14:

Ok, I see the error and the configuration in your config.log.

The short answer is you are missing the package qt4-dev-tools on your system.
You should install it if you want to keep building Octave with Qt 4. But you
should definitely move to Qt 5 especially because you are on a recent enough
Ubuntu.

If someone wants to look at fixing this, the error is that
/usr/bin/qcollectiongenerator is found by configure and set as the variable
QCOLLECTIONGENERAOR. Same with qhelpgenerator. But those files in /usr/bin/
are just symlinks to qtchooser, regardless of whether the sub-packages that
provide qcollectiongenerator and qhelpgenerator for a given version of Qt are
actually installed.

I believe this has come up before because the Qt package can be quite
confusing. Octave's configure script has to try to figure out all the possible
ways Qt libraries and tools can be installed without getting so complex that
we can't maintain it.
