+Subject: [PATCH] libweston,tools: Include libgen.h for basename signature
+
+Latest musl has removed the declaration from string.h [1] as it only
+implements POSIX version alone and string.h in glibc implements GNU
+version of basename. This now results in compile errors on musl.
+
+This might be a warning with older compilers but it is error with
+Clang-17+ as it treats -Wimplicit-function-declaration as error
