+	  Enable stack smashing protection support using GCCs
+	  -fstack-protector-all option.
+
+	  See http://www.linuxfromscratch.org/hints/downloads/files/ssp.txt
+          for details.
+
+	  Note that this requires the toolchain to have SSP
+	  support. This is always the case for glibc and eglibc
+	  toolchain, but is optional in uClibc toolchains.
