+Subject: [PATCH v2] mesh: Move local basename into utility file
+
+Defining an override via a missing.h can prove difficult when a file
+needs to use basename and dirname both the APIs and needs to include
+libgen.h for them, in such situations there will be signature clash
+for basename function.
