You had no conf/local.conf file. This configuration file has therefore been
created for you with some default values. You may wish to edit it to use a
different MACHINE (target hardware) or enable parallel build options to take
advantage of multiple cores for example. See the file for more information as
common configuration options are commented.

### Shell environment set up for builds. ###
You can now run 'bitbake <target>'
Common targets are:
core-image-minimal
core-image-sato
meta-toolchain
meta-toolchain-sdk
You can also run generated qemu images with a command like 'runqemu qemux86'
