Add a workaround for a bug in some binutils version which strictly

interpret whitespace as macro argument delimiter. Since the code is
preprocessed by gcc and the tokenizer may insert whitespace, that can
fail. http://sourceware.org/bugzilla/show_bug.cgi?id=669

The same change was committed in r3044 to the AMD CAR code.
