Followup to r15323. Cannot use AC_GCC_WARNING_SUBST to detect
whether -Wformat-security is supported. Special handling is needed.

gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2  accepts -Wformat-security
without -Wformat being present on the command line. Other GCC
versions will issue a warning if -Wformat is missing. r15323
adds -Werror to AC_GCC_WARNING_SUBST and therefore turns that
warning into an error.  With the consequence that
-Wformat-security appears to be unsupported -- a false conclusion.
