When configuring canadian cross toolchain and you're unlucky enough to be

 using a build and host that are different, but that config.sub thinks mean the same thing,

 you might end up without BUILD_CC being defined as 'cc' or 'gcc',

 which might cause $CC to be used instead, which would be wrong...
