[Automake-NG] [FYI] {elisp-work} coverage: byte-compiling elisp files in different subdirectories

[Stefano Lattarini]

Where a '.el' file in a subdirectory might require a '.el' file in
another one.  This does not work out of the box, but can be made to
work with a judicious use of $(AM_ELCFLAGS) (just introduced in the
previous commit).

* t/lisp-subdir-mix.sh: New test.
* t/list-of-tests.mk: Add it.
