[Skiboot] [PATCH 15/18] doc: Use parallel builds

[Oliver O'Halloran]

Using all your cores makes re-building the documentation a significantly
faster. It'd be even faster if sphinx would stop assuming every single
.rst file changes between builds, but casual googling didn't reveal a
fix so -EEFFORT. Might be a bug in Sphinx 1.8.3 which Fedora is shipping.
