+# there is no other way to identify defconfig builds, QTI internal
+# representation of perf builds (identified using the string 'perf'),
+# is used to identify if the build is a slub or defconfig one. This
+# way no critical debug feature will be enabled for perf and shipment
+# builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT
