[Qemu-block] [PATCH v3 1/2] Makefile: add nit-picky mode to sphinx-build

[John Snow]

If we add references that don't resolve (or accidentally remove them),
it will be helpful to have an error message alerting us to that.

Turn warnings into errors so we can be alerted to problems in building
the documentation when they arise.
