From 98586d6dc598e40b8b821b0dde57599e188a7ca4 Mon Sep 17 00:00:00 2001

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]
