Yes.

I'm building this change right now:

+    (arguments
+     `(#:configure-flags (list "--enable-expensive-hardening"
+                               "--enable-gcc-hardening"
+                               "--enable-linker-hardening")))

Taken from Gentoo, I trust their hardening project to debug and
discover good usage.
