Details:

When Qt is not found, or if --disable-gui is given, the dist target works but
produces an octave source distribution without the libgui subdirectory. Trying
to build that source package fails because configure requires
libgui/Makefile.in.

The easy solution would be to disable make dist like we do when docs are
disabled. But that is mainly because we definitely want the documentation to
be in the source distribution, right?

It should be possible, and would be nice, to be able to run make dist without
Qt, assuming there are no EXTRA_DIST files under libgui that are generated
using any of the Qt tools. I think that's the case but I'm not sure.

Automake definitely allows conditional SUBDIRS that will be entered for dist
and distclean targets but not for other make targets.

I discovered this on a Hydra build, where Octave is being built without Qt (so
far) and make dist is used to produce a source package that is then built on
i686-linux and x86_64-linux. See for example
http://hydra.nixos.org/build/4397119/log/tail-reload
