Not Necessary to Define __NuttX__ in Make.defs

PR-2192 (commit 9208176f600d0d04446531909bf05710716a5ee4) refactors definition of the __NuttX__ preprocessor symbol to tools/Config.mk, so it is no longer necessary to define it in each board's Make.defs file.

If you are using NuttX on a custom board not in the NuttX repository, you may want to make a similar change to your Make.defs files.

Remove lines like this:

ARCHDEFINES = -D__NuttX__

Or remove -D__NuttX__ from lines like this:

CXXFLAGS += $(ARCHDEFINES) $(EXTRAFLAGS) -pipe -std=c++11 -D__NuttX__
