+#    Description:
+#      This file is the makefile for the GNU binary utilities
+#      (binutils).
+#
+#      The following set of packages MUST be a matched set:
+#
+#	 * Target Binary Utilities
+#        * Target GNU C Standard Library
+#        * Target GNU C++ Standard Library
+#        * Target GDB server and client
+#	 * Host Cross Binary Utilities
+#	 * Host Cross Compilers
+#        * Host Cross GDB client
+#
+#      These are presumed provided by the tool chain and are simply
+#      sourced from it rather than built anew from source.
+#
+#      However, for tool chains that do NOT provide target-based
+#      binutils (e.g. CodeSourcery Sourcery G++), this source-built
+#      instance should provide a reasonable alternative. NOTE though, not
+#      having binutils matched to the tool chain can result in sometimes
+#      undefined results.

+# We could also handle this by removing DESTDIR and setting the prefix
