+Subject: [PATCH] tools/hex2hcd: fix musl compatibility
+
+The call to basename() relies on a GNU extension
+to take a const char * vs a char *. Let's define
+a trivial helper function to ensure compatibility
+with musl.

+Subject: [PATCH] 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.
