Subject: [PATCH] Skip tests if test subdir is missing

Problem reported by Jeffrey Walton in:
https://lists.gnu.org/r/emacs-devel/2019-05/msg00041.html
* Makefile.in (CHECK_TARGETS): New macro; use it
to simplify 'check' and similar rules.
($(CHECK_TARGETS)): If tests are missing, do not fail
after issuing a diagnostic.  Just skip the tests.
