So can the modules be just moved into their own separate files and #included
(or INCLUDEd)?
Or add something like dg-additional-sources for module compilations, where
dg.exp would compile those files ahead of compiling the particular testcase,
and the testcase would contain dg-final cleanup lines for all those modules (so
every test would be self-contained).
