As of the cyclic-dependency fix in b01173c6b7, building from our tarball
using the instructions in its README (using the source tree as build
tree), in the absence of Halibut, would lead to the pre-built man pages
not being installed.
(Also, a load of "Could not build man page" complaints at cmake
generation time, which is how I actually noticed.)
