Indeed, there is no particular guide. Porting Python first will likely tell
you a whole lot about the general process. You can search in the numpy
source for "NPY_CPU" (and "PPC" and "ARM") to see where we have applied
architecture-specific customizations. I suspect that you will have more
trouble dealing with the OS (or lack of OS, if that's the case) than the
architecture itself.
