Created attachment 650256 [details, diff] Minimal patch
Sphinx and its dependencies are 16 new packages. Many users have LLVM installed only as library needed by other packages and do not need to read LLVM man pages. Would patch adding IUSE="man" be accepted?

Most importantly, this fixes the build failure due to trying to build HTML docs when sphinx is available but recommonmark is not. As a side result, this may prevent some unnecessary targets from being built and delay some others into src_test().
