Michael Ho 2fa0b3278c rootfs_ipk: allow do_populate_sdk in parallel to do_rootfs
Switch do_populate_sdk for the ipk package manager to use a separate target
opkg config file and separate the lockfiles restricting do_rootfs and
do_populate_sdk from running in parallel.

This way if an image recipe includes a dependency to do_populate_sdk by
default then it will run in parallel to do_rootfs saving time compared to the
sequential execution.

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.
