Add an error that indicates that a module provides no sources, either
because it is faulty or only provides submodules (like encoding does).

[PATCH hare 2/3] hare::module: Expose that module only contains a readme
Export this patch
If mod.srcs.only_readme is set, the current module is empty and hare
should not continue with the compilation. However with only that check
is present 'make check' fails, with the message 'module hare is empty'.
To prevent this, don't check for empty modules if ctx.test is true.
