octave.mk MXE file still necessary?

[Rik]

All,

I just checked the recipes for making in Octave in the MXE src/ directory
and I find stable-octave.mk (4.4.0), default-octave.mk (5.0.0), and
octave.mk (4.2.0-rc4).  Do we need the last recipe?  I think it is
confusing because without any other information I would think to build just
octave.mk, and that would get me a very out-of-date version.
