+	  Sourcery CodeBench toolchain for the x86/x86_64
+	  architectures, from Mentor Graphics. It uses gcc 4.6.3,
+	  binutils 2.21.53, glibc 2.15, gdb 7.2.50 and kernel headers
+	  3.2.10. It has support for the following variants:
+	    - Intel Pentium 4, glibc, 32 bits
+	      Default for x86, nothing special to do.
+	    - Intel Atom, glibc, 32 bits
+	      Select an Atom core
+	    - Intel Xeon, glibc, 64 bits
+	      Default for x86_64, nothing special to do.
+	    - Intel Core 2, glibc, 64 bits
+	      Select a Core 2 core
+	  Other architecture variants (beyond Pentium-4/Xeon) are
+	  supported as well, but glibc is not optimised for it.
