Instead use --preprocessor-arg; in binutils 2.36, the --preprocessor flag was changed so that it no longer accepts a string containing multiple arguments, but the whole --preprocessor argument is treated as the path to the preprocessor executable (where the path can contain spaces). It's currently unclear whether this behaviour will stay or if it is going to be reverted in the future, see discussion at [1]. Just to be safe, avoid using the --preprocessor argument. Don't redeclare the full preprocessing command, but just add the $(CC_DEPFLAGS) options. Based on a patch by Kyle Schwartz.
