+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]

+Subject: [PATCH 1/2] Use correct CFLAGS for extensions when cross-compiling
+
+Take PY_CFLAGS_NODIST into account, like in native build. This is needed
+in order to to profile-optimized build. Also, pass EXTRA_CFLAGS to
+profile-optimized build.
