Paul Barker 816a12758b bitbake: fetch2/gitsm: Make need_update() process submodules
If the bitbake.srcrev nugget is not present for the commit we're
interested in we should not just bail out and say that an update is
needed. Instead we can recursively walk through the submodules and check
for the presence of the required commits.

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.
