[oe] [meta-oe][PATCH 1/4] llvm2.9: add LLVM_EXTRA_ARCH to enable X86 unless building for x86

[Martin Jansa]

* now I see why it was there before, at least on arm it fails with:
  | CMake Error at cmake/modules/LLVMConfig.cmake:127 (message):
  |   Library `X86' not found in list of llvm libraries.
