--- Comment #1 from Segher Boessenkool <segher at gcc dot gnu.org> --- "If you build a little-endian compiler". What does that mean? A cpu=powerpc76le* compiler? Or something else? Note that *any* compiler can be used as little-endian, by just using -mlittle. Nothing more, nothing less. It should work no matter what is the default.
