The upstream MXE project seems to have a way to build multiple 
toolchains at once.  Unfortunately, merging MXE and mxe-octave might be 
difficult at this point.  If we want to take advantage of the MXE 
project's work in the future, I think the best bet is to use what we've 
learned with mxe-octave and port the necessary changes back to the MXE 
project, then simply use that to build the packages.  The rules to build 
an Octave installer or tar/zip based distribution would then be a 
separate layer on top of MXE.

In case anyone is wondering why things diverged so much, I forked 
mxe-octave from MXE when it appeared that there was no interest in the 
MXE community for building shared libraries.  Since then, the situation 
has changed and it might be time for another look and possibly 
eliminating the fork.
