The standard GCC preprocessor we use to preprocess device tree sources
files has a whole bunch of macros predefined, among which
This causes a property like 'linux,code' to be converted into '1,code'
which is obviously wrong. So let's get rid of all the predefined macros
by passing -undef to the preprocessor command line.

How did you make it not throw them away?
(I can find a few suggestions online, neither sounds optimal.)
