Richard Purdie 0899c332f7 bitbake: runqueue: Fix recidepends handling
Currently we only run through the recidepends/recrdepends code once. This
means that we can miss some expansions of dependency trees where one
rec{r,i}depends tasks depends on another rec{r,i}depends task.

In reality we need to iterate over the data until we stop adding
dependencies.

In doing this we can't show quite so granular progress information since
we don't know how many times we'll need to do this.

This does slow down the runqueue prepare phase however some optimisations
are possible and can be handled in subsequent patches.

This fix means some missing dependencies, such as:

<image>:do_fetchall -> <image>:do_rootfs -> <pkgs>:do_package_write_X
  -> <ca-certs>:do_package_write_X -> debianutils-native
(via PAKAGE_WRITE_DEPS)

are now found/added.

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.
