Apparently, libffi has no supported for microblaze, and it seems that
libffi is a mandatory dependency for building Python. It looks like you
have two options:

 *) Port libffi to Microblaze

 *) Use a more lightweight scripting language such as Lua. Python is
    quite heavy for MMU-less systems at 100-180 Mhz such as Microblaze
    systems. Lua is probably a much better fit for this kind of systems.
