Quentin Schulz d97ad8cf1a docs: sphinx: yocto-vars: rebuild files when poky.yaml has changed
poky.yaml changes aren't detected by Sphinx by default.

In order to detect changes in poky.yaml, its md5sum is stored in the
app.outdir (BUILDDIR/html when building html) and checked against the
md5sum of the poky.yaml under use.

If the md5sum has changed, find all rst files in app.srcdir that have at
least an occurence of `&.*;` and mark them as requiring a rebuild.

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.
