+Subject: [PATCH 2/2] Makefile: add target to split profile generation
+
+We don't want to have profile task invoked from here and want to use
+qemu-user instead. Split the profile-opt task so qemu can be invoked
+once binaries have been built with instrumentation and then we can go
+ahead and build again using the profile data generated.
+
+Upstream-Status: Inappropriate [OE-specific]
