define _COMPILING_NEWLIB for all targets when compiling 

The _COMPILING_NEWLIB symbol is for declaring "the code is being
compiled for newlib itself" so headers can change behavior vs the
header being used by users (who should get the normal clean API).
Unfortunately, this symbol is defined inconsistently leading to it
only being useful for a few subsections of the tree.

Pull it out so that it's defined all the time for all targets.
