Some quick questions that come to mind:

 * What happens if we have Micropython installed next to the regular
   Python 2 or Python 3 interpreters / standard library on the same
   system? Do they conflict or not?

 * What about all the Python external modules (package/python-*/) we
   have in Buildroot? Do they work with Micropython?

Nitpick: use the standard header for all packages. You lack an empty
line before and after the package name. See all other Buildroot
packages. Ditto for the micropython package.

You should define MICROPYTHON_LIB_LICENSE as well.
