+Subject: [PATCH] login-utils: include libgen.h for basename API
+
+musl has removed the non-prototype declaration of basename from string.h [1] which now results in build errors with clang-17+ compiler
+
+include libgen.h for using the posix declaration of the funciton.
+
+Fixes

+../util-linux-2.39.2/login-utils/su-common.c:847:20: error: call to undeclared function 'basename'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
