Nathan Chancellor 8884fc918f powerpc: Fix fatal warnings flag for LLVM's integrated assembler
When building with LLVM_IAS=1, there is an error because
'-fatal-warnings' is not recognized as a valid flag:

  clang: error: unsupported argument '-fatal-warnings' to option '-Wa,'

Use the double hyphen version of the flag, '--fatal-warnings', which
works with both the GNU assembler and LLVM's integrated assembler.
