+    aarch64 (arm64) isn't a supported architecture for exp-sgcheck.
+    
+    exp-sgcheck/pc_main.c contains:
+    
+       #if defined(VGA_arm) || defined(VGA_arm64)
+          VG_(printf)("SGCheck doesn't work on ARM yet, sorry.\n");
+          VG_(exit)(1);
+       #endif
+    
+    But exp-sgcheck/tests/is_arch_supported checked against uname -m
+    which returns aarch64 (not arm64). Fix the test check so the
+    exp-sgcheck tests are skipped instead of producing failures.
