Khem Raj 6a8f66ab23 base.bbclass: Add python3-native to native paths for hg fetcher
This helps fix an issue where python interpreter in hg script could
overflow the BINPRM_BUF_SIZE which is 128 on most of systems, because
interpreter is hardcoded and build paths can be deep.

This patch helps, because now the absolute python interp path in hg can
be replaced with '/usr/bin/env python3' and it will ensure that python3
from native install is used instead of the one on host.

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.
