Robert Yang e236735d45 bitbake: build.py: check dependendent task for addtask
The following command is incorrect, but was ignored silently, that may suprise
users:

addtask task after task_not_existed

This patch can check and warn for it. It would be better to also check "before"
tasks, but there is no easier way to do it.

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.
