Also, the above completess correct as the error is not fatal to the build. This was caused by: commit d72b08017161ab385d4ae080ea415c9eb7ceef83 Author: Ian Munsie powerpc: Add ability to build little endian kernels The below fixes this by testing for the -mbig-endian option before adding it. I've not done the same thing in the little endian case as if -mlittle-endian doesn't exist, we probably want to fail quickly as you probably have an old big endian compiler.
