+	  Sourcery CodeBench toolchain for the amd64 (x86_64)
+	  architectures, from Mentor Graphics. It uses gcc 6.2,
+	  binutils 2.26, glibc 2.24, gdb 7.11 and kernel headers
+	  4.7. It has support for the following variants:
+	    - AMD Puma/Jaguar (family 16h), glibc
+	    Default for x86_64, nothing special to do.
+	    - AMD Steamroller (family 15h), glibc
+	    Select a steamroller core.
+	  No other architecture variants are supported since glibc
+	  is optimized for one of these two baselines.
