Ross Burton f59e9cc356 python-native: don't cause a full regeneration of the built sources
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.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
