After properly setting PKG_CONFIG_PATH and restarting "make" in 
./mxe-octave top dir, I found that the build got as far as octave itself.
It stopped with "no space left on device" but that is obviously my side 
of things. (Good to know that this joke needs some 2.5 - 3 GB disk space 
all together)
Another 2-3 hour wait I suppose.....
