niko.mauno@vaisala.com 22ce3c1206 package_manager.py: Explicit complementary fail
When running bitbake -c populate_sdk <image_name>, it is expected that
packages matching SDKIMAGE_INSTALL_COMPLEMENTARY name mask (unless
declared in PACKAGE_EXCLUDE_COMPLEMENTARY) are installed to resulting
SDK. Underlying mechanism issues a package manager install call for set
of complementary packages. However the mechanism doesn't seem to inform
the user all too obviously in case the package manager command behind
install_complementary() method fails -- and since it is combined with
attempt_only=True option, user might end up wondering why several *-dev,
*-dbg packages are missing from resulting SDK.

Improve associated install() method behaviour in affected OpkgPM and
DpkgPM classes so that a problematic state of affairs becomes directly
obvious for bitbake user, resulting in shell output like:

  WARNING: someimage-1.0-r0 do_populate_sdk: Unable to install packages.
  Command '...' returned 1:
  Collected errors:
   * Solver encountered 1 problem(s):
   * Problem 1/1:
   *   - package somepkg-dev-1.0-r0.x86 requires somepkg = 1.0-r0, but
         none of the providers can be installed
   *
   * Solution 1:
   *   - allow deinstallation of someotherpkg-1.1-r1.x86

   *   - do not ask to install a package providing somepkg-dev

   * Solution 2:
   *   - do not ask to install a package providing somepkg-dev

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.
