Good advise, so the kernel patch can be revised to:

diff --git a/tools/perf/Makefile b/tools/perf/Makefile
index 067f2df..071986c 100644
--- a/tools/perf/Makefile
+++ b/tools/perf/Makefile
@@ -497,7 +497,7 @@ else
 		BASIC_CFLAGS += -DNO_NEWT_SUPPORT
 	else
 		# Some releases like Fedora has /usr/include/slang/slang.h other than /usr/include/slang.h
-		SLANG_INC ?= -I/usr/include/slang
+		SLANG_INC ?= -idirafter /usr/include/slang
 		BASIC_CFLAGS += $(SLANG_INC)
 
 		EXTLIBS += -lnewt -lslang

---

With this, we might not have to touch perf.bb. So seems like we'll use
this solution? :)

Thanks,
