+Subject: [PATCH] fix parallel building
+
+Producing two target with on command results in a race condition:
+Both targets are requested, the command is executed twice, and the target
+are overwritten randomly.
+Solution: Run the command for on target and let the second depend on it.
+Then touch the second to make sure it's newer.
