+-lutil to work.  Rather than impacting them with having to change

+Subject: [PATCH] malloc: Fix malloc debug for 2.35 onwards
+
+The change 1e5a5866cb ("Remove malloc hooks [BZ #23328]") has broken
+ports that are using GLIBC_2_35, like the new OpenRISC port I am working
+on.
+
+The libc_malloc_debug.so library used to bring in the debug
+infrastructure is currently essentially empty for GLIBC_2_35 ports like
+mine causing mtrace tests to fail:
+
+    cat sysdeps/unix/sysv/linux/or1k/shlib-versions
+    DEFAULT                 GLIBC_2.35
+    ld=ld-linux-or1k.so.1
+
+    FAIL: posix/bug-glob2-mem
+    FAIL: posix/bug-regex14-mem
+    FAIL: posix/bug-regex2-mem
+    FAIL: posix/bug-regex21-mem
+    FAIL: posix/bug-regex31-mem
+    FAIL: posix/bug-regex36-mem
+    FAIL: malloc/tst-mtrace.
+
+The issue seems to be with the ifdefs in malloc/malloc-debug.c. The
+ifdefs are currently essentially exluding all symbols for ports > 2.35.
+
+Removing the top level SHLIB_COMPAT ifdef allows things to just work.
+
