+commit 89423f5d8ba05a099c2c62227a00a4f4eec59eb3

+    Intercept stpcpy also in ld.so for arm64
+    
+    On other arches stpcpy () is intercepted for both libc.so and ld.so.
+    But not on arm64, where it is only intercepted for libc.so.
+    
+    This can cause memcheck warnings about the use of stpcpy () in ld.so
+    when called through dlopen () because ld.so contains its own copy of
+    that functions.
+    
+    Fix by introducing VG_Z_LD_LINUX_AARCH64_SO_1 (the encoded name of
+    ld.so on arm64) and using that in vg_replace_strmem.c to intercept
+    stpcpy.
