When cross-compiling Python 2 you need a native pgen binary, but the cross
recipe can't do this on it's own so we build it in python-native and install it.

The rule to build pgen was also causing a complete rebuild of all of the
generated sources, which meant that building Python 2 needs a *host* Python 2.

This can be fixed by simply building pgen, as this is all we need to install.

[ YOCTO #13645 ]
