Jaewon Lee 88db9e41c1 populate_sdk_ext: Introduce mechanism to keep nativesdk* sstate in esdk
When doing a devtool build-sdk from within an esdk all nativesdk
components would be rebuilt. This patch introduces SDK_INCLUDE_NATIVESDK
flag to toggle the inclusion of nativesdk packages when creating the
esdk sstate

Currently locked-sigs.inc is generated during do_sdk_depends which
doesn't pull in nativesdk packages. Generating another locked-sigs.inc
in do_populate_sdk_ext and pruning it to only nativesdk* packages by
using a modified version of the already existing function
prune_locked_sigs and merging it with the current locked-sigs.inc
Also adding SDK_INCLUDE_NATIVESDK tasklistfn to the logic surrounding
setting tasklist file to not prune esdk sstate during creation

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.
