-         If your target CPU does not have a Floating Point Unit (FPU) or a
-         kernel FPU emulator, but you still wish to support floating point
-         functions, then everything will need to be compiled with soft floating
-         point support (-msoft-float).
+         Some builds may require a 'biarch' toolchain. This option

+                 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.
