+                 If you're specifying an addition target architecture,
+                 you'll probably need to also provide options to make
+                 the compiler use this alternate arch.
+
+                 For example, if you're building a compiler that can build
+                 both powerpc and powerpc64 binaries, you'll need to
+                 specify -m64 here.
