I will send a v2 where I combine the passing
{TARGET|HOST}_CONFIGURE_OPTS into their respective environments. I
will also send changing of the setuptools package type as well.

I'm not familiar with the setuptools build method for building with
python but I would image that it doesn't hurt to pass _CONFIGURE_OPTS
in the environment.
