Bruce Ashfield e66d183b9e perf: change dependencies on python to python3
The upstream kernel can now handle python3 for the perf scripts, coupled
with the impending EOL of python2, we switch the dependencies in perf
(scripting) to python3.

Outside of dependency changes, we also pass the following two variables
to the perf build: PYTHON=python3 PYTHON_CONFIG=python3-config. To
ensure that our python3 components are used.

For configurations that disable perf scripting, there is no change in
behaviour.

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.
