I see the C preprocessor as an optional feature, instead of a rule
everybody must follow.

In fact, adding this rule here requires that each board configuration
must be changed. And for all of them, running the preprocessor is
unnnecessary.

What about to add this rule only to the Makefile of the boards that
require preprocessing ?
