Im assuming you ran configure in the mxe-octave directory and its not issues 
with that.

Mxe-octave was based on an older version of mxe, where I believe there was only 
a PKG_BUILD target being called, so you need to create a section for:

define $(PKG)_BUILD
endef

and in it call the correct target build


Some of the dependencies you have haven't been built in a long time, so may be 
rather out of date, or no longer compile in mxe-octave, but I guess you will 
find that out soon enough if that’s the case.
