+MACHINE variable can be set up in conf/local.conf file under build directory
+or via command line, e.g.:
+
+    $ MACHINE=<supported_machine> bitbake <target>
+
+You can also run generated qemu images with a command:
+
+    $ DEPLOY_DIR_IMAGE=tmp-newlib/deploy/images/qemu-x86 runqemu qemux86

flavours/zephyr/local.conf.sample

+#
+# This file is your local configuration file and is where all local user settings
+# are placed. The comments in this file give some guide to the options a new user
+# to the system might want to change but pretty much any configuration option can
+# be set in this file. More adventurous users can look at local.conf.extended
+# which contains other examples of configuration which can be placed in this file
+# but new users likely won't need any of them initially.
+#
+# Lines starting with the '#' character are commented out and in some cases the
+# default values are provided as comments to show people example syntax. Enabling
+# the option is a question of removing the # character and making any change to the
+# variable as required.
+
+#
+# Machine Selection
+#
+# You need to select a specific machine to target the build with. There are a selection
+# of emulated machines available which can boot and run in the QEMU emulator:
+#
+#MACHINE ?= "qemu-cortex-m3"
+#MACHINE ?= "qemu-x86"
+#
+# This sets the default machine to be qemu-x86 if no other machine is selected:
+MACHINE ??= "qemu-x86"
+
+#
+# Default policy config
+#
+DISTRO = "zephyr"
+
+#
+# Package Management configuration
+#
+# This variable lists which packaging formats to enable. Multiple package backends
+# can be enabled at once and the first item listed in the variable will be used
+# to generate the root filesystems.
+# Options are:
+#  - 'package_deb' for debian style deb files
+#  - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
+#  - 'package_rpm' for rpm style packages
+# E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
+# We default to rpm:
+PACKAGE_CLASSES ?= "package_rpm"
+
+# CONF_VERSION is increased each time build/conf/ changes incompatibly and is used to
+# track the version of this file when it was generated. This can safely be ignored if
+# this doesn't mean anything to you.
+CONF_VERSION = "1"
