[FYI 1/2] {maint} coverage: expose automake bug#12372 (tags-related)

[Stefano Lattarini]

That bug is somehow already been fixed in the latest automake
version (1.12.4); but exercise it anyway in the testsuite, to
ensure we won't regress.

* t/tags-pr12372.sh: New test.
* t/list-of-tests.mk: Add it.
