Christopher Larson 2d6a3655e9 bitbake: fetch2/git: fetch shallow revs when needed
When bitbake determines if a git clone needs updating, it only checks for the
needed srcrevs, not the revs listed in BB_GIT_SHALLOW_REVS, which will fail if
using shallow and the needed rev was added to the upstream git repo after a
previous fetch. Ensure that we also check for shallow revs.

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.
