So? Relying on a help message from sphinx-build would just make
our makefile fragile.

btw, it didn't work here:

	$ ./sphinx_latest/bin/sphinx-build --version
	sphinx-build 8.2.3

	 $ ./sphinx_latest/bin/sphinx-build  -M help
	Error: at least 3 arguments (builder, source dir, build dir) are required.
