4Subject: [PATCH 2/2] Makefile: add target to split profile generation
5
6We don't want to have profile task invoked from here and want to use
7qemu-user instead. Split the profile-opt task so qemu can be invoked
8once binaries have been built with instrumentation and then we can go
9ahead and build again using the profile data generated.
