So you are saying that the Lisp part of a module should be installed
under /usr/share/emacs/site-list, and it's shared-library part under
/usr/lib?  Wouldn't this complicate things?

I'm not sure I understand the problem: doesn't a module normally come
with a Lisp interface file?  And if so, couldn't the module solve this
inside the Lisp part, e.g., load the shared-library file explicitly?
IOW, why do we need to treat this situation specially?

Failing that, how about arranging for architecture-dependent
subdirectories under site-lisp instead?
