Joshua Watt c3271dca21 bitbake: bitbake: cache: Fix error when cache is rebuilt
It is expected that load_cachfile() returns an integer indicating how
many entries were loaded from the cache. In the event the cache needs to
be rebuilt, 0 must be returned to prevent python from attempting to add
an None and an integer together.

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.
