Nicolas Dechesne a69d74c842 sphinx: report errors when dependencies are not met
To build the Sphinx documentation, we have the following dependencies:
* sphinx
* sphinx_rtd_theme
* pyyaml

If any of these dependencies are missing, we might end up with some
cryptic error messages. This patch adds better error reporting when
dependencies are not met.

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.
