+Subject: [PATCH] hack: testing -Wl,-fuse-ld=gold does not work correctly on
+ hardened
+
+Not sure why this test falsely passes with the hardened compiler when it
+normally will report the following error:
+
+    ld: -f may not be used without -shared
+
+But apparently the default options hardened uses makes interpreting the
+option as -f valid usage. For reference the option is:
+
+    -f name
+    --auxiliary=name
+        When creating an ELF shared object, set the internal DT_AUXILIARY
+        field to the specified name.  This tells the dynamic linker that
+        the symbol table of the shared object should be used as an
+        auxiliary filter on the symbol table of the shared object name.
+
+This in turn causes a stray library to show up in ldd output:
+
+    use-ld=gold => not found
+
+Which seems mostly harmless but does cause some confusion.
