+Subject: [PATCH] tests regression: fix failure on older versions of Make
+
+Older versions of Make will choke on the # character in the $(shell
+expression, treating it as the beginning of a comment. Resulting in
+the following error
+
+make unterminated call to function 'shell': missing ')'.  Stop.
