+Subject: Don't pass MAKEFLAGS to $(MAKE)
+MIME-Version: 1.0
+Content-Type: text/plain; charset="utf-8"
+Content-Transfer-Encoding: 8bit
+
+make will pass them automatically. Also they are not meant to be
+consumed by make as they are stripped:
+
+Thus, if you do ‘make -ks’ then MAKEFLAGS gets the value ‘ks’.
