Chen Qi 20b0c638ba oe-depends-dot: print dependency chains for '--why' option
When using '--why' option, we currently only list elements.
It's better to print out dependency chains. This patch adds
such abitility.

e.g.
  $ oe-depends-dot -k util-linux -w recipe-depends.dot
  Because: packagegroup-core-boot systemd-compat-units systemd shadow core-image-minimal dbus e2fsprogs
  core-image-minimal -> packagegroup-core-boot -> systemd-compat-units -> systemd -> dbus -> shadow -> util-linux
  core-image-minimal -> packagegroup-core-boot -> systemd-compat-units -> systemd -> dbus -> e2fsprogs -> util-linux

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.
