+Subject: [PATCH 2/2] build: enable serial-tests automake option (for ptest)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For ptest, we need to be able to compile the tests without
+running them.
+
+Enabling the serial-tests automake option will add
+buildtest-TESTS and runtest-TESTS makefile targets, the
+former being what we want.
