Before automake 1.11 doing this would have contributed a lot of noise to
the build logs, but silent mode should cover this.

For simple cases like this it seems okay - in cases where we were
exporting the definition in a .h file a more complex solution may
be required.

One nit/question, should it be CPPFLAGS instead of CFLAGS?
