build opts: add MI_example to NULL ISA

A later changeset changes the file src/python/swig/pyobject.cc to include
a header file that includes a header file generated at build time depending
on the PROTOCOL in use.  Since NULL ISA was not specifying any protocol,
this resulted in compilation problems.  Hence, the changeset.
