+Subject: [PATCH] Add helper function for basename
+
+musl does not provide GNU version of basename and lately have removed
+the definiton from string.h [1] which exposes this problem. It can be
+made to work by providing a local implementation of basename which
+implements the GNU basename behavior, this makes it work across C
+libraries which have POSIX implementation only.
+
+Upstream-Status: Submitted [https://sourceware.org/pipermail/elfutils-devel/2023q4/006727.html]
