Add '-undef' to DTS_CPPFLAGS to avoid unwanted expansion of dts

Example: A number of PowerPC related *.dts files in the kernel define
a property named 'linux,network-index' which (w/o '-undef') is
expanded to '1,network-index' by the preprocessor because of '#define
linux 1.'
i think you should use -ansi instead. that's what we use in other
places for the same reason.
this would increase the probability of a name clash.
no idea what you're talking about. have you actually looked at the
output of `gcc -E -dD -ansi` ?
$ gcc -E -dM -ansi - </dev/null | wc -l
229
$ gcc -E -dM -undef - </dev/null | wc -l
2
and ? did you *look* at the output ? they're all of the form __foo__.
i already considered that.
do any device trees really use __foo__ names ? i don't think so.
is there any drawback using '-undef' in this particular case besides
"we use -ansi in other places for the same reason"?
