Newer llvm/clang versions (since r102686) have a __clang_version__ macro which can be used to print the exact clang version. Fix a case where chip_to_probe was referenced twice via extern, once at the function level and once in a global include file. Found by latest clang. Corresponding to flashrom svn r1087.
