+commit d5a3ca4061f7adc59196fa58e34eacebbebcbcfe
+Author: Florian Weimer <fweimer@redhat.com>

+
+    Implement run-built-tests=no for make xcheck, always build xtests
+    
+    Previously, the second occurrence of the xtests target
+    expected all xtests to run (as the result of specifying
+    $(xtests)), but these tests have not been run due to
+    the the first xtests target is set up for run-built-tests=no:
+    it only runs tests in $(xtests-special).  Consequently,
+    xtests are reported as UNSUPPORTED with “make xcheck
+    run-built-tests=no”.  The xtests were not built, either.
+    
+    After this change always, xtests are built regardless
+    of the $(run-built-tests) variable (except for xtests listed
+    in $(tests-unsupported)).  To fix the UNSUPPORTED issue,
+    introduce xtests-expected and use that manage test
+    expectations in the second xtests target.
