    newlib: move nano-malloc logic from build to source files
    
    Simplify the build system logic a bit by moving the mallocr.c ->
    nano-mallocr.c redirection from the Makefile to the source files.
    This allows for consistent object name usage regardless of the
    configuration options used in case a machine dir wants to define
    its own override.
