+Subject: [PATCH] fix err variable and function conflicts
+
+There comes below build failure with musl when
+ptest enabled.
+| In file included from ../../elfutils-0.176/tests/dwfl-proc-attach.c:33:
+| ../../elfutils-0.176/lib/system.h:63:35: error: called object 'err' is not a function or function pointer
+|  #define error(status, errno, ...) err(status, __VA_ARGS__)
+|                                    ^~~
+| ../../elfutils-0.176/tests/dwfl-proc-attach.c:92:5: note: in expansion of macro 'error'
+|      error (-1, 0, "dwfl_linux_proc_attach pid %d: %s", pid,
+|      ^~~~~
+| ../../elfutils-0.176/tests/dwfl-proc-attach.c:79:7: note: declared here
+|    int err;
+|        ^~~
+
+It is because there is no error.h in musl and
+the patch 0008-build-Provide-alternatives-for-glibc-assumptions-hel.patch
+has updated to use err.h to replace error.h
+and also added macro definiton as below when
+use musl.
+ #define error(status, errno, ...) err(status, __VA_ARGS__)
+
+And in err.h, there is below logic:
+_Noreturn void err(int, const char *, ...);
+
+But when ptest enabled, there comes below error
+as there is both variable and function defined
+to be err in tests/dwfl-proc-attach.c.
+So change the err variable's name to workaround
+the build failure with musl.
+
+Upstream-Status: Inappropriate [workaround in musl]
