No, because *.elc files are platform-independent, whereas *.eln files
are platform-dependent.  It is conceptually incorrect to put them in
the same directory, and also against the Posix tree rules.

First, this is a concern for test suite as well.  And besides, what
you suggest is a general feature, not something for the test suite
alone, AFAIU.
