+Subject: [PATCH] x86-linux-setup.c: Use POSIX basename API
+
+Musl C library only supports POSIX basename function. while glibc has
+both GNU extention as well as POSIX basename implemented. Switch to
+using posix version, so it can work across musl and glibc
+
+basename prototype has been removed from string.h from latest musl [1]
+compilers e.g. clang-18/GCC-14 flags the absense of prototype as error.
+therefore include libgen.h for providing it.
