Which Help features are those? The files that Help uses are already installed 
into the etc or lisp subdirectories of /usr/share/emacs/27.0.50 (or whatever).

I looked through the Emacs source code, and the only use of source-directory 
that seemed relevant was find-function-C-source-directory; is that what you were 
referring to? If so, the problem can be addressed by installing the C sources 
into /usr/share/emacs/27.0.50/src/*.[chm], which is something we should be doing 
anyway since the build directory might be missing or (worse) wrong when someone 
wants to look at the sources of the installed Emacs. In the old days installing 
the C sources might have been thought too heavyweight but those days are long gone.
