If this is just a problem with some of the build tools you can try to 
skip them by eliminating them from the list of tools in Makefile.in.

We build tools like m4 in mxe-octave so that we can try to ensure new 
enough versions are availble for building all the other tools and 
packages.  But if you have a modern system, that's probably not 
necessary.  It's worth a try to eliminate the build-* packages that 
don't work and use the versions of those tools that you already have 
installed on your system.
