BaseTools/tools_def: suppress GCC predefined macros in DTB compilation
The standard GCC preprocessor we use to preprocess device tree source
files has a whole bunch of macros predefined, among which
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1
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.
